Huge psf file!! Cannot allocate memory

SPA1984

Hello,

I made an Ocean script to do a transient analysis. When I try to plot or export the waveforms the system gives me a message like "Cannot allocate mamory for the transition file". The psf file has a 56,6GB weigh.

I also try to save a txt file using the command ocnPrint, but when the simulation is done, the system gives me the same error.

Is there the possibility to generate several psf files? One for each waveform.

Is there any function to save the a txt file for each one of the 16 waveform on the fly? This way, the system doesn't have to handle this amount of memory.

I'm using Results Browser in ADEL  with aps simulator.

Thank you very much.

  • Which version of the tools (help-> about in the CIW) are you using? Have you tried using psfxl as the output format? Also running "virtuoso -64" to run in 64 bit mode to allow greater memory access. 

     Note, ocnPrint still has to load the signal into memory, so that's unlikely to help. The size of the file shouldn't be so critical because it doesn't load the entire file in memory - but if the individual signals have a huge number of points, that may be a problem. 

     Regards,
