reading SST2

[danmc]

Is there any library I can link to from a C program which provides the
capability to read SST2 simulation results?

One of my biggest complaints over the years about spectre is that it
is a pain to interface in house post simulation analysis tools to
spectre. I'd like to take advantage of the newer format but if I have
no way to access the results, I can't.

To completely re-implement the post simulation analysis tool in skill
or matlab would be considerable work and probably run slower than a
compiled tool.

Using a document file format would be the best and would really help
out many cadence customers, but a library one could link to that
provided results access would be the 2nd best thing.

It seems that even the old fall back 'psf' program is no longer an
option with sst2.

Thanks

i think if u go to Waveform viewer and save as *.dat
u can directly load the file in matlab and view it

but I need to access many many many waveforms. Far too many to plot
them each time in a waveform viewer.

There is a "spectre" toobox for matlab since MMSIM61. It's in
<mmsimInstDir>/tools/spectre/matlab

It's covered in the SpectreRF Theory manual (chapter 1, I think).

Also, in MMSIM62, in
<mmsimInstDir>/tools/spectre/examples/SpectreRF_workshop/SpectreRF_AN
there are a couple of Matlab related app notes.

Dan,

Check if the Ultrasim Waveform Interface (UWI) is documented.

If it is, you could write your own writer for tran analysis results
using UWI.
For that you should provide Spectre simulator with a shared library
plugin and specify "-format uwi -uwilib your_so_lib" in the command
line.
