Unable to run cds_srr commands in matlab

findsriharsha over 4 years ago

Here is my simple matlab script:

import cadence.srrdata.*
import cadence.Query.*
import cadence.utils.*

resdir = '/nfs/sc/disks/xyz_dts_tb/maestro/results/maestro/Interactive.47/1/xyz_noise/psf';

datasets = cds_srr(resdir);

Here is the error:

You need to have closer alignment between the MATLAB and Spectre versions. You're using Spectre from 2019 and MATLAB from 2016. Because the cds_srr stuff uses a shared library, there's a requirement to use aligned compiler versions.

I reproduced the same issue you did running on my RHEL7.6 machine, using the same version combinations. If I use MATLAB R2020a with SPECTRE19.1 then it works fine. Also if I used MATLAB R2016a with SPECTRE16.1 it also worked OK (I didn't check the range of working versions - there is a support matrix in the documentation and on support.cadence.com if I remember rightly).

MMSIM Spectre, APS, SpectreRF and Matlab support matrix is the Article that Andrew is talking about.
