  • The MMSIM version is not relevant here, because I was using the data you produced - the MMSIM version might affect how the psf directory is generated, but not how it is read.

    I've never seen a case where the same data, the same version and the same expression behaves differently. My guess is that something has changed so I'm not doing precisely what you're doing.

    For example, I ran viva from the command line, used the results browser to open the psf downloaded from your last attachment, and then pasted the expression from my post into the calculator. Then hit the eval button and it worked fine.

    If that doesn't work for you then I can only suggest that you contact http://support.cadence.com as I have no idea what it could be - we'd probably need to do a web screen sharing session to see what you are seeing.

    Kind Regards,
