How to reinvoke a simulation by changing some testbench code in Simvision?

Saru K S

In simvision how to reinvoke a simulation when some testbench code is changed such that the changes are included after the reinvoke ?

Thanks in advance!

  • If you compiled and ran with a single xrun command, then the SimVision menu "Simulation -> Reinvoke Simulator" does exactly what you want, it'll recompile and load the new simulation snapshot ready to re-run.

    If you compiled using a separate xrun command, you might get away with re-running that manually, then in SimVision use the reinvoke as above. The only gotcha is that xrun puts a NFS lock on the xcelium.d (working) directory to prevent you recompiling whilst running the simulation. You can bypass that with the -nolock switch but then the onus is on you to avoid crashing simulations by recomipling. We don't really recommend this flow at present.
