    pss simulation insufficient memory problem Reply

    I was trying to run a typical pss/qpss simulation of a mixer circuit. The simulation always crashes, saying insufficient memory. I checked the system resource, and was sure that system resource (including memory) was littlely used. Did anyone has similar situation and any tips to solve the problem? Otherwise I have to run transient simulation and do dft to check the result which is very painful. I am using icfb 5.10.41_USR3.27.

    Thanks in adance.

    Without getting into the details of your RF simulation, try reducing your data points, using the swapfile option, using the new parser (+csfe), and finally, 64bit Spectre.

    I strongly suggest using a newer version of Spectre (the USR3 version you are using dates back 2005). There have since been memory handling improvements in Spectre. Try using IC5141USR5 or better MMSIM6.2.

    A thorough list of suggestions is available here:

    So far, swap-file and save-selected, both in the output option and simulator option, help quite a bit. Though sometimes still get that crash issue.
