Problems visualizing results with Wavescan - MMSIM 6.2 - IC 5.1.14

yoyega

 Hi, I am using MMSIM 6.2 with IC.5.1.14. I have to run a large tran simulation with spectre and I've been having problems at the moment of visualizing the results with wavescan. According to sourcelink solution 11264780 I should set the following variable to have the tran.tran file broken up in 2GB files: setenv PSF_WRITE_CHUNK_MODE_ON true. So I have set this environment variable, but I still have only one tran.tran file of 70GB. Is there a solution for this?

 

Thanks,

Pedro

  • First of all, sorry about the breaking the rules - I really do apologize. I'll keep that in mind from now on (except for this post :) ).

    Thank you very much for your time and a very thorough and clear answer - I really do appreciate it.

    It did hit my mind to reduce the number of points in the simulation, but once I got hooked on this format issue, I really wanted to go through it to the end.

    From your answer I understood that it already is at the end. Namely,

    1. in order to do SP analysis, psfbin is the format used anyway, there is no choice (at least for my version of software).

    2. psfbin allows chunks only for transient analysis, so I am limited to a 2 GB file anyway.

    Therefore, in order to do my analysis, the only way out is to reduce the accuracy of the simulation, be it reducing the number of points or the number of parasitics or any other way.

    Once again, I am very greatful - thank you very much.
