Why do the Murata capacitors and inductors not simulate correctly in Hspice?
The Murata capacitors and inductors use frequency dependent resistors and inductors in the model. This frequency dependency is difficult to account for in Hspice and currently the simulator only uses a single frequency when generating the Hspice netlist.
The solution is to first use the Murata parts in AWR to generate an output s-parameter file. Then import the s-parameter file back into AWR and use that in any schematic that is being used for Hspice simulation. The software will accurately take the s-parameters into Hspice.
