Virtuoso AMS Simulation Error

SQ202407156826 over 1 year ago

Greetings,

I ran into this error " *Error* eval: unbound variable - _GLOBAL_amsEMSHandle " while trying to run a simple AMS sim in virtuoso. Does anyone have an idea what caused this issue?

My virtuoso version is ICADVM181, with INCISIVE152.

Thanks in advance.

Siyun,

Please see *Error* eval: unbound variable - _GLOBAL_amsEMSHandle netlist error in AMS Designer

Also, why are you using INCISIVE152 - it's an obsolete 9 year old release, which was replaced by the XCELIUM stream (with many versions since, as it has a 6-monthly release cycle). ICADVM18.1 is also old (the last version was in 2020) - essentially the article I point to suggests using a version later than ICADVM20.1 ISR22. The problem occurs if you have a second maestro session open in the same Virtuoso with spectre as the simulator. I think that if you close that second maestro view then it will be OK (probably - this happened some considerable time ago so I don't have the time to test).
