Simulation and PEX

AllenD

Hi Team

Can I please confirm something about simulation and Calibre PEX?

I am currently running a transient simulation and a small part of my circuit is using calibre PEX  for post layout simulation purpose. 

During that simulation, which takes a long time, I created a layout2 view for that small part of the circuit and changed some drawings and PEXed again. Then I realized that the PEX generated Calibre view is updated, even though the simulator is using the previous PEX result. 

I believe this update of Calibre pex view will not interfere with the current simulation in running, because the data from the previous PEX is used when I click "netlist and run" and the simulator stop using the PEX result once the simulation actually started,

Can you please confirm?

Thanks

Allen

    Hi Allen,

    It won't impact the simulation, since that's just using the netlist that was produced prior to the simulation starting. However, it might affect your ability to probe signals within the Calibre extracted view after simulation, since the probe points don't match the netlist. However, if probing outside of the pex view, you would be fine.

    Regards,

    Andrew.
