I am developing a custom function in Cadence's calculator to do some advance analysis from simulation data. I know how to read cadence's simulation data from matlab (using measure functions), after performing matlab transformation of simulation data, I want to write it back to cadence (possibly in PSF data format) so that cadence can read the data and plot it. Can someone tells me whether this approach make sense? And is there any functions available to write the matlab data back in PSF format?
IMHO makes no sense.
1. PSF is a proprietary waveform format of Cadence, you will not
find any specification or documentation about.
2. The Analog Waveform Display (AWD) which evaluated the PSF will be replaced
finally in DFII 6.1. by WaveScan which has the wave form format SST2.
So you would develop something for a dead end.
The best would be if Cadence would support an open waveform standard.
There are change requests for this, but as far as I know there has not much
happened in this direction.
In reply to Bernd:
Is SST2 a cadence proprietary waveform format also?
How about the calculator function flow? Has anyone try to use it to interface with matlab?
In reply to vlau2:
A couple of comments here.
1) PSF supports an ASCII mode which is pretty easy for creative coders to write to and the "psf" executable can converts ascii to binary and back if the ascii performance is not acceptable. Just take any psf file and run the "psf" executable on it and you will see the ascii output (% psf tran.tran)
2) PSF and SST2 are both proprietary formats also Cadence does as part of its OASIS simualtion integration to ADE provide access to writing PSF but you must purchase this integration kit to gain access. For newer formats like SST2, access is not provided.
3) I've shared in my feedback to the subject "How to plot a graph" (Feb09) the process of using "csv" files to import external data into WaveScan & ViVA XL as this is pretty simple as well as the option to use the calculator function "getAsciiWave".
4) If you have VCD data then you can easily convert to SST2 using the simvisdbutil exectuable that comes in the IUS (AMS) hierarchy.
Hope these options help,
