matlab interface and PSF data format

vlau2

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?

    Hello Andrew, 

    Thanks for the reply, and sorry for positing a out-of-topic message. I was looking for alternatives to skill to run my simulations and posprocess the results in the context of analog/RF circuits. Python or matlab are both good.  I know the video and know the integration with matlab. I use it.  I am not sure if the new version would  allow me to control the simulations from matlab. One of the strengths that make spectre/ocean the default standard 20 years ago was that all of it was easily controlled and scripted using lisp at that time a state of the art tool(Skill). Unfortunately with the years this is really outdated. Skill lacks way behind compared with matlab/python in numeric or plotting capabilities, not without mention easy to use and number of existing libraries. As the complexity of the verification grows the solution by CAD vendors seems to go to more complicated GUIs, but that would not be sustainable as the number of corners, complex optimizations is growing much rapidly that anyone can make a GUI. In my opinion a good API in any of the two language that can also run the simulations is required so a single script can control variables, run simulations and pos-process the results.

    In Python or Matlab  we can implement complex optimization algorithms for our circuits or using similar pos-processing algorithms that we will use during measuring. In some way the solution now is what cadence did 20 years ago.  The best simulator, as still spectre-RF is, with a state-of the art scripting language.
