We face a issue when use Ansys do simulation.
Â
Â
we set the same simple testbench to load  cphy IBIS model ,but find they have different results in Primesim pro(Finesim ) and Ansys with same testbench.
- We can see the voltage change of the ABC single-ended in finesim is correct ,but in Ansys, The voltage has become very strange
- I hope you can provide technical support to help us solve this problem
Ansys without verilogA

For technical support you can open a case in Ansys Customer Support Space (ACSS) under customer.ansys.com

Yes, if you are full Ansys customer, please open a support case so we can take a closer look. If not, we can try and give some more general advice here. First off, I don't see any finesim results, just Ansys Circuit waveforms. But I am also curious what IBIS models you are using here. I really have not seen much in the way of traditional IBIS models being used for MIPI c-phy as IBIS was never really intended to produce the 3 level output signaling that s-phy requires.Â

Hi @Dan Dv
I have this IBIS case that I need help from ansys engineer or AE.
There may be some NDA between synopsys and ansys, so we need set a meeting to fix it.

Hello Zhishuang,
That is not something that we can handle through this forum. Once you have opened a ticket in our system, one of our technical support engineers will be able to follow up with you on this regard.Â
Best regards,
