AWR's Script Development Environment (SDE) allows you to create and execute macros and utilities to automate complex tasks from within the AWRDE. The SDE supports scripting in Visual Basic and includes syntax highlighting and powerful debugging capabilities.

The Scripting Editor contains BASIC script modules that you can run from the program by choosing Scripts > Global Scripts or Scripts > Project Scripts directly, or from within the SDE.

The language used in scripts is SAX Basic, a subset of Microsoft® Visual Basic® for Applications. SAX Basic language online Help is available here:  AWR_V13_API_Diagram.pdf 

Components of the Script Development Environment

To open the SDE, choose Tools > Scripting Editor or click the Scripting Editor toolbar button. The AWR SDE window opens.  

The following table describes the components of the SDE:

ProjectScript Project Browser (or simply, Project Browser). Allows you to create scripts to automate tasks within the AWRDE. The scripts display as two subnodes. The first subnode, Global, contains global modules. The second subnode, Untitled Project.emp contains project-specific modules also called local modules.
MenusA set of menus: FileEditViewInsertDebugRun, and Help. Most of the menu choices and commands are also available as buttons on the toolbar.
Script workspaceThe area in which you design, run, and debug scripts.
Immediate/Watch/Stack windowThe area in which you can print the results of a running script and watch the value of the variables during the debugging process.
Toolbars (Standard, Debug, and Edit)A row of buttons that provides shortcuts for editing, running, and debugging scripts; creating new Code Modules; accessing VBA Object Browser Help; adding available references to a Project; and for accessing Immediate, Watch and Quick Watch Windows.To view a tooltip for a particular toolbar command, pass the cursor over the button.


Project Browser

The scripting browser is along the left side of the SDE and organizes the scripts available in the project. Scripts can be either global or local to a project. If a script is general purpose, you should save it as a global script. If the script only works with a specific project, you should save it as a local script.

Local Modules 

Shown in the scripting browser with the name of the project, in this example “Untitled Project.emp.”  Local scripts are saved in the project, so if you copy your project file to another machine, your scripts are automatically included.  

Global Modules

Scripts stored in the Scripts or ScriptsUser folders are included in this. From the AWR Design Environment, select Help > Show Files/Directories to find these folders. Scripts folder contains the factory scripts shipped with the product installer.  ScriptUser contains global scripts that the user manages. Global scripts are available to all projects. The Global subnode contains all global scripts that are stored separately in individual *.bas files located in specific folders on your computer.  You can add a new *.bas file to your ScriptUser folder, then right-click the Global node and choose Check For New Files to make the new script available.

To define more than one global script folder, add the following line in your User.ini file:

                [File Locations]

where <path> is the full or relative path to the folder to search for additional *.bas files. You can add more than one path by separating paths with semi-colons. PDKs can also specify a scripts file location, so scripts can be shipped with PDKs and loaded automatically as global scripts.

Speed Menus

Right-click in the scripting browser to get the following menu commands:

View CodeOpens that code module for editing.
Run Sub MainRun the Main subroutine in that code module.
Insert ModuleInsert a new code module.
RenameRename the selected module.
RemoveRemove (delete) the selected module.
ExportSave the module to disk as a .bas file.
PrintPrint the selected module.
ImportImport a module from disk (only in Local Modules). You will be prompted to browse for a .bas file to import
Check for New FilesAdd any new files in the global locations to the SDE (only in Global Modules).


Developing Scripts 

The code can either be in code modules or object modules.  Code modules contain procedures that run from start to finish when executed.   This is useful for creating macros or procedures for automating tasks that you would normally perform manually.  Each module will begin with a 'Sub Main', and each code module is listed the project browser as a separate item.   To create a module, right-click the Global or the local node and choose Insert Module.  A new module is added to the node, and a new window will be opened with the 'Sub Main" defined.  

' Code Module
Sub Main
End Sub

An Object module runs code in response to events generated by the AWRDE object. Object modules do not have a Sub Main that executes when they run. Instead, they contain special functions called Event Handlers that execute in response to events that objects start. When run, the Basic engine waits for an event to occur, such as adding a schematic to the project. When the event occurs, the associated event handler code executes.  

To enter the code that responds to an event, expand the project tree for the local scripts, into the Object Modules node and double click on the node named ThisProject.  Note: we do not support global object modules at this time.   In the code editor window, select the object that starts the event from the object list (this will be called Project for events from the AWR API), and then select an event from the Proc list. After you select an event, a handler procedure is added to the module, and you can add any additional code you want to execute. The following figures show this process.


The following code is added to the code editor window. 

 Private Sub Project_NewSchematic(Schematic As MWOffice.Schematic)

End Sub

Before the code can respond to events, you must run the module by clicking the Run button on the toolbar. 

Next time you open the project containing object modules, a  dialog box will appear asking if you would like to enable or disable macros.

If you choose Disable Macros, the object module will not be running.  You can immediately edit the code, and you will need to click Run on the toolbar to be able to respond to an event. 

If you choose Enable Macros, the object module will be running.  You will need to click End on the toolbar to be able to edit the code, and the AWRDE will be automatically responding to events.   

If you set the option, Always use the settings and do not warn again, the dialog will not show again for that project. If you need to change the settings and to have the dialog, there will be an entry in the user.ini file.  Search for the project name in the user.ini and remove the entry for the warning about the script. 




To work with different automation clients and their objects, you should create a reference to a COM components type library using the following steps in the SDE:

  1. Click the References button on the toolbar or select Edit > References from the menus. A list of references similar to those shown in the following figure displays.

  2. Select the checkbox next to the reference you want to add.

  3. If the desired reference is not listed, click the Browse button and locate the type of library you want to use.

The AWRDE object library is selected by default and references must be set for the object module and each code module separately.   Each checked reference is searched in order from top to bottom.

Object Browser

The Object Browser shows information about all the special data types that are available.

To open the object browser in the SDE, click the object browser button on the toolbar or choose View > Object Browser from the menus

The following figure shows the object browser with the AWRDE (MWOffice) type library selected.

Note: more modern SDEs might provide more insightful object browsers.   For example, creating a script in Microsoft Excel, adding a reference to the AWR type library and then using the object browser shows like below. 

Object and Proc Lists

The Object and Proc lists are shown at the top of any code or object module. 

The object list shows all the objects in the current module

  • The (general) object groups all of the procedures which are not part of any specific object.
  • When in an object module, you can also select Project

The Proc list shows all the procedures (list of all subroutines and functions) for the current object.

  • Selecting a procedure that is not bold inserts the proper procedure definition for that procedure, this mostly applies to object modules.  
  • Selecting a procedure that is bold will arrange the file such that the selected procedure is in view. 
  • (declarations) takes you to the beginning of the file for where global variables can be defined. 

Status Bar

The status bar gives more information about what is happening with the code.  The right side of the status bar also lists the file line number for the cursor.  


Auto-completion in the IDE uses the object browser information to show the current object's methods and properties.

For example, when you type "project.", you will get a list of the available objects available under the Project object.  

As you continue typing, it will match the closest child object and will be highlighted.  For example, typing "project.sch" will show as below.  

Notice the object that is highlighted.  If you press the Tab key, that object is completed.

To see language extensions, built-in instructions/functions, and user-defined procedures/variables press Ctrl-Space on a blank line in the IDE.

Referencing Subroutines and Functions in Other Files

If you want to reference subroutines or functions in other *.bas files, there are several options. Referencing code can be a good way to track common groups of code you want to reuse and easily update. 

Stand-Alone File on Disk

To reference subroutines and functions in a stand-alone file

Use the following in your script:

 '#Uses "global.bas"
Sub main
End Sub			

The path to the file can be an absolute path or a path relative to the AWR Project file in which you are working.  The disadvantage of this approach is that you cannot debug into any referenced functions.

Another Script Loaded in the SDE

To reference subroutines and functions in another script loaded in the SDE for that type (Global or Project)

Use the following in your script:

 '#Uses "*global"
Sub main
End Sub		

Notice a few differences. There is no path to the file. You use a "*" before the name. You do not use the '.bas'  extension for the file.

NOTE: You cannot reference items in a Project level script in Global scripts, nor items in a Global level script in Project scripts. 

Getting Help

When typing code, press the F1 key to display Help for the specific word the cursor is over. If the cursor is over a component that belongs to the AWR API, the AWRDE Help opens to the appropriate section.  Newer Microsoft operating systems do not support the help system build into the current SDE.  We recommend you use the PDF documentation to understand the SAX basic specific commands.   

Debugging Scripts

There are various techniques to debug scripts that will be described below.

Break Bar

The break bar shows which lines have breakpoints. It also shows which line is next to execute. Clicking on the break bar toggles the breakpoint for that line.  Alternately, the Debug > Toggle Breakpoint will toggle the current line of the cursor to have a breakpoint or not.   

Stepping Through Code

When your code has stopped at a breakpoint, you have various options; the options are available from the Debug menu.   See the menu listings below for the hotkeys.  

  1. Step Into - Steps to the next line of code and into any subroutes or functions. 
  2. Step Over - Steps to the next line of code and over any subroutes or functions.
  3. Step Out - If in a subroute or function, step out of the procedure to the next line of code. 
  4. Run To Cursor - Run to the current location of the cursor.   

When you run the script after a breakpoint, the code will run to the next breakpoint or to completion.     

Immediate Window

The immediate window is automatically displayed above your code.  Use your mouse to drag the divider between the code and the Immediate window to change how big each one is relative to the window size. The Immediate window is used to evaluate an expression, assign a variable or call a subroutine.

  • Type "?expr" to show the value of "expr".
  • Type "var = expr" to change the value of "var".
  • Type "Set var = expr" to change the reference of "var".
  • Type "subname args" to call a subroutine or built-in instruction.
  • Type "Trace" to toggle trace mode. Trace mode prints each statement in the immediate window when a macro/module is running.  


Watch Window

The Watch window is automatically displayed above your code when the code paused during debugging.  The Watch window is used to list the variables, functions, and expressions that are calculated and displayed.

  • Each time execution pauses the value of each line in the window is updated.
  • The expression to the left of "->" may be edited.
  • Pressing Enter updates all the values immediately.
  • Pressing Ctrl-Y deletes the line.
  • Add variables to the Watch window typing the name and typing Enter.  Alternately, when the code is paused, put your cursor over a variable and select Debug > Add Watch.

Stack Window

The Stack window is automatically displayed above your code when the code paused during debugging. The Watch window is used to list the lines which called the current statement.

  • The first line is the current statement. The second line is the one that called the first. And so on.
  • Clicking on a line brings that macro/module into a sheet and highlights the line in the edit window.

Debug.Print Statement

You can use the 'Debug.Print' statement to print values of variables.   The values will be printed in the Immediate window for you to view. 

You can also use the 'Debug.Clear' statement to clear out the contents of the Immediate window.  

Note:  you can copy and paste from the Immediate window

User Forms

 UserDialog is described by a Begin Dialog...End Dialog block. To graphically add a UserDialog place the current selection in the code where you want the dialog and select Insert > UserForm from the Scripting Development Environment.  

The following will display:

Use the controls on the left to add items to design your form.  Hover your mouse over each item to understand what they are for.   When you are done, close the dialog, and the code for the form will be inserted into your script. 

To graphically edit a UserDialog place the current selection in a UserDialog block and select Insert > UserForm from the Scripting Development Environment.  The dialog will open to edit the previously created form.   

The following code is an OK and Cancel button.   

Begin Dialog UserDialog 400,203 ' %GRID:10,7,1,1
		OKButton 50,161,90,21
		CancelButton 210,161,90,21
	End Dialog
	Dim dlg As UserDialog
	Dialog dlg

When you have a cancel button, you need to return a value from the dialog to make decisions.  Below is the code changed to handle a cancel button press. 

' Code Module
Sub Main
	Begin Dialog UserDialog 400,203 ' %GRID:10,7,1,1
		OKButton 50,161,90,21
		CancelButton 210,161,90,21
	End Dialog
	Dim dlg As UserDialog
	rtn =Dialog(dlg)
	If rtn = 0 Then 'cancel pressed
	End If

After adding a control, double-click to edit properties for each control.  The example below is a text field in a dialog. 


There are options for the dialog itself.  You double click anywhere in the editor, not on a control item.   

The Caption field will be the name of the dialog, and the Dialog Function name is to reference the function to do advanced dialog controls.   

The example below shows both fields entered. 


When closing the dialog with the Dialog Function field filled, you will get the prompt below.    You usually would click next, and then the shell of the dialog function code will be added.   



With the form looking like below,

the code in the editor will be.  

' Code Module
Sub Main
	Begin Dialog UserDialog 400,203,"My Example Dialog",.examplefunction ' %GRID:10,7,1,1
		Text 30,21,270,28,"AWR Example Text",.Text1
		OKButton 30,105,90,21
		CancelButton 140,105,90,21
	End Dialog
	Dim dlg As UserDialog
	Dialog dlg

End Sub

Rem See DialogFunc help topic for more information.
Private Function examplefunction(DlgItem$, Action%, SuppValue&) As Boolean
	Select Case Action%
	Case 1 ' Dialog box initialization
	Case 2 ' Value changing or button pressed
		Rem examplefunction = True ' Prevent button press from closing the dialog box
	Case 3 ' TextBox or ComboBox text changed
	Case 4 ' Focus changed
	Case 5 ' Idle
		Rem Wait .1 : examplefunction = True ' Continue getting idle actions
	Case 6 ' Function key
	End Select
End Function


Running Scripts from the AWR Design Environment


You can run scripts directly from the AWRDE Scripts menu.  Scripts display either one of three areas. 

  1. Custom Name
  2. Scripts > Project Scripts
  3. Scripts > Global Scripts

 The list that displays is in the format<module name>(<sub name>). Any Sub in a given module that takes no input arguments is available in this list. You can hide any such sub by using the Private declaration before the name of the subroute. For example, the following figure shows a macro named "example" that has three subroutines, a,b, and c.



Notice that the third sub is declared private. If you choose Scripts > Project Scripts you can access only the first two subroutines  as shown in the following figure.



You can control how scripts display in the Scripts menu. Above any Sub, you can add a line that defines the folder in which to display the script. This line is in the form '$MENU=name where name is the desired folder name. The name of the sub displays under that folder. You can use the folder name "hidden" to prevent that sub from displaying. For example, you can add the line "' $MENU=Data" to display this script under the Data sub menu. Only one level of folders is allowed. When you use this syntax the script is only in this folder; it is no longer in the Scripts > Project Scripts or Scripts > Global Scripts folders. Because of this structure, AWR recommends that you write your scripts with one Sub Main that uses the hidden folder tag, and then give your code a meaningful name that you then call from the Sub Main. This is because you need a Sub Main to run the script from the SDE, but you want a meaningful name when running the script from the Scripts menu. The following example scripting code demonstrates these various concepts.


' $MENU=hidden 
sub main 
	end sub 
' $MENU=Layout 
	Sub Delete_Unassociated_iNets
End sub 

The following figure shows how this script displays in the AWRDE menu.



Notice that there is a folder named Layout and a script named "Delete_Unassociated_iNets" under that folder.

You can use menu, toolbar, or hotkey customizations to run any macro. See “Customizing Toolbars and Menus” and “Customizing Hotkeys” for details on customizing these objects. When customizing, look for the Categories setting equal to Macros.  You only should customize global scripts since they are guaranteed to be available to run in each project opened.
