Hi, John,
We too use HSIM in a similar manner to Seema and I completely agree with
everything she states. I would add that using the HSIM Analog Artist
Interface made our transistion from shifting from Spectre/spectreVerilog
to HSIMd very smooth. There are some drawbacks to using the integrated
version -- specifically an inability to use it as a mixed mode simulator
via the interface but ability to use it stand alone is a huge drawback.
Having said that there are the obvious work arounds, and it should be
stated that's why they want you to use their Co-Sim AAI as well..
