This new SPB16.2 feature allows Allegro AMS Simulator (PSpice) customers to simulate split parts as single components. The PSpice engine can identify different sections of a split part and simulate them as a single component by intelligently combining the sections into one single part. At present, the Split Part support is available only in the AMS-DEHDL flow.DetailsThe Split Part feature has been provided to allow users the ability to simulate large parts that cannot fit onto a single schematic sheet or the user wants to split the part for easier generation of the schematic (cosmetic preferences). Prior to the SPB16.2 release, the AMS Simulator (PSpice) netlister did not recognize the split part and would give warnings during the PSpice net listing process. The simulation results were also not as expected because of this. With this feature, the PSpice netlister will gather connectivity information for all instances of split parts and merge them into a single instance.AMS Simulator uses the two properties - SPLIT_INST and LOCATION - to identify split part sections and combine them. Alternatively, the SPLIT_INST_NAME property can be used to identify sections of a split part.Considerations while working with split parts in AMS-DEHDL flow:
As always, I welcome your feedaback and suggestions about how to use this new capability.
