CDS_SRR doesn't

wgtkan

Hello:

My MMSIM version is MMSIM151

Spectre version is spectre181

sub-version  18.1.0.235.isr3

The Linux operation system is: Red Hat Enterprise Linux Workstation release 6.7 (Santiago)

My Matlab version is R2018B.  I have read all the previous posting regarding interfacing Matlab with Spectre. I have RF toolbox version 3.5.

I followed  Andrew Beckett’s excellent example on how to interface Matlab with Spectre by reading this post:   https://community.cadence.com/cadence_technology_forums/f/rf-design/21507/working-with-dc-sweeps-and-op

and this post: https://community.cadence.com/cadence_technology_forums/f/rf-design/22435/interfacing-spectre-parametric-analysis-result-to-matlab-in-command

The cds_srr function doesn’t exist in the Matlab and when I read the spectreuser documentation, it mentions about the Multi_mode  Simulation (MMSIM) Toolbox for Matlab but not in detail. I do not seem to find the MMSIM documentation. I get the error that says Undefined function or variable 'cds_srr' in Matlab.

What function should I use?

Thank you very much in advance.

    OK, first of all you don't need both SPECTRE and MMSIM in your path - SPECTRE supersedes MMSIM.

    You need to do this:

    setenv MATLABPATH `cds_root spectre`/tools/spectre/matlab/64bit

    or

    setenv MATLABPATH `spectre_root`/tools/spectre/matlab/64bit

    To ensure the cds_srr utility (the Spectre toolbox) is in your path. BTW, the Matlab "RF" toolbox isn't needed for this.

    Regards,

    Andrew.

    BTW, for the documentation, it's not in the Spectre User Guide. It's in the Spectre RF Theory. Simplest thing is to run <SPECTREinstDir>/bin/cdnshelp and search for "matlab". You'll then find one of the hits is the "The Spectre/RF MATLAB Toolbox"
