PAC Simulation: outputperiod option

ahchang

I want to do a time integration of my PAC simulation over one period. I did the simulation and I obtained a pac.real.pac file.  For some reason, I could not read the result from this file the same way as other files.  The normal Cadence command does not allow me to read data from pac.real.pac and I also cannot see the result directly from ADE (Results Browser or Direct plot).  Does anyone know how to open the simulation result from such file?



Thank you,

Albert


As an example, I can only see the following outputs even though the file pac.real.pac exists in the psf folder.

   'pss-td.pss'
   'pss-fd.pss'
   'pac-pac'
   'modelParameter-info'
   'element-info'
   'outputParameter-info'
   'designParamVals-info'
   'primitives-info.primitives'
   'subckts-info.subckts'
   'variables'

    My understanding has always been that the outputperiod was an option added in the early days of SpectreRF to allow R&D to debug things, and as far as I know it does not  behave sensibly - for example, if you sweep frequency in the pac analysis, you get a combined waveform for all the points. I suspect at some point the logFile has been incorrectly updated, or ViVA not checked to ensure it supports this output file.

    In practice, I think the outputperiod option is of no use. As far as I can see, there have been no service requests or CCRs on this option, so my assumption (since there are things about it which don't work), is that nobody has tried to use it either.

    If you wish to persue this further, please log a service request via http://support.cadence.com so that this can be discussed with R&D further, but I don't believe it is intended to be a useful option for users. In fact I am tempted to request that the option be removed...

    Best Regards,
