What is the format of the psf transient simulation?

[Svenn Are Bjerkem]

Hi,

does anybody happen to know what binary format the tran.tran.trn and
tran.tran.dsn files in the psf directory is? I can use the psf utility
to inspect the dc.dc and all the other binary result files in the psf
directory and to extract particular values, but the transient
simulation seems to have changed format. I am working on 5.1.41 in a
fairly standard setup.

Does cadence provide a utility to read those files? I want to generate
some reports, and find working with something like psf utility quite
convenient.

Nevermind, I found that Cadence save transient signals to sst2 format
as default in 5.1.41. Once I recognised that sst2 is another cadence
format, a search on sourcelink gave me the way to turn on psf for
transient simulations again.

I would still like to know if there is a utility to read specific
signal waveforms from the command line, though.

There is the matlab "spectre toolbox" which is in MMSIM61 onwards. But that's
not quite from the command line... and you can use OCEAN of course.

In other words, there's no equivalent of the "psf" command for sst2 data.
