Strobing Problem

Dushan

Hi,

 I am running a pss sweep analysis and using strobing to save only certain number of points (50). Then I open the results in a table and save them in csv format for further processing. Sometimes it works perfectly, but sometimes it produces more than one point around some of the time instances (closely spaced - around 1fs or even less), so the total number of points is incorrect (e.g. 52 instead of 50). Any help with this issue?

I am running icfb sub-version 5.10.41_USR5.90.69.

 Thanks,

Dusan

  • Dusan,

    I've not seen this before. I have seen the case where the strobe points are not precisely on the strobe period - which can happen if there are multiple points (e.g. caused by a boundstep in a verilog-a module) near the strobeperiod. If they're too close, it will just keep one of them and not honour the strobeperiod precisely (note that if this happens, the resulting point will be extremely close, so as not to make any difference in practice).

    What spectre version are you using? You mentioned the icfb version, but it's the  spectre version that is more important (this will appear in the top of the spectre.out log file).

    Regards,

    Andrew.
