AWR Version 13
Using Custom Spirals in Analog Office
It is easy to create your own custom spiral inductors within the AWR environment. The following simple steps show how to create the spiral element, characterise it and then use it in your project.
3) Open up the layout view. Drag one of the pins so they are no longer on top of each other.
2) Click on the elements tab and look under subcircuits. Here you will find the subcircuit called Spiral. Add it to your schematic.
6) Double click on the Extract block and select the Mesh tab. Turn off "Model as zero thickness".
9) Set the project frequencies then run your simulation. The simulation will now run plotting the Inductance and Q over frequency.
Option 1 is to simply use the device as is within your project. It can be used multiple times within that project by selecting it from the subcircuits menu. It will be extracted each time a simulation is run.
Option 2 is to create an s-parameter file by right clicking on Output Files > Add Port parameter File. This s-parameter file can then be imported and used as a model for the spiral so no further extractions of the spiral are carried out during simulations. This s-parameter file can easily be imported into other projects. Similarly the GDSII can also be exported and then imported into new projects.
Option 3 is to make an s-parameter model then generate an xml component linking symbol, layout, s-parameter model together as an element in the users own custom library. See the Knowledge base for information on creating custom XML components.
