Undefined function or variable 'cds_innersrr'.

findsriharsha

Hello,

For the below cds_srr function  call, I am getting error in matlab. could you please suggest if it is a known bug or if there is any workaround available?

Please let me know if you need more details.Thanks

Tool Version:

Matlab version: R2015A

MMSIMHOME=/p/hdk/cad/mmsim/14.10.804
MMSIM=/p/hdk/cad/mmsim/14.10.804
MMSIM_OVERRIDES_VER=14.10.804.0

CODE: struct_n = cds_srr(c.outfile, c.sweep, params_

Error:

Undefined function or variable 'cds_innersrr'.

Error in cds_srr (line 20)
sig = cds_innersrr(dirname, dataset, signame, verbose);

Error in techsweep_spectre (line 58)
struct_n = cds_srr(c.outfile, c.sweep, params_n{1});

  • Correction:

    Code: struct_n = cds_srr(c.outfile, c.sweep, params_n{1});

  • Most likely you've either set the $MATLABPATH variable incorrectly, or have used the addpath in Matlab to add the wrong directory.

    What you need is:

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

    or similar. In other words, you need the add the path to the MMSIM installation with tools/spectre/matlab/64bit on the end. If you've missed out the 64bit part, you'll get the problem you're seeing (this is because Matlab for the last few years is only available in 64-bit mode). We probably should obsolete the old 32-bit libraries...

    Regards,

    Andrew.

    Sorry for the delayed response: This is what $MATLABPATH is set to...

    (Setup)(hiphdk)(I76A0)> echo $MATLABPATH

    Matlab script:

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

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

    datasets = cds_srr(resdir);

    See my response to your duplicate post (not sure why you posted it twice - the forum guidelines ask you not to do this.
