Failed to install Spectre/RF matlab toolbox

candygg

Hello, Thank you for viewing my post. I met a problem when first time use the Spectre/RF Matlab toolbox.

I use MMSIM6.2 and Matlab2010b(32bit), run on 32bit Linux.  Where&How should I set LD_LIBRARY_PATH and MATLABPATH?
I try to set them in ~/.cshrc file. The codes are appended to the existing .cshrc file as following:
setenv LD_LIBRARY_PATH `cds_root spectre`/tools/dfII/lib:`cds_root spectre`/tools/lib/
setenv MATLABPATH `cds_root spectre`/tools/spectre/matlab

Then I lauch matlab from home directory and type "getenv LD_LIBRARY_PATH" in matlab window to check the path. It looks ok.
The spectre paths are appended to matlab's own paths. Then I tried the matlab code:

rdir='XXXX/XXXX/XXX/spectre/schematic/psf'
datalist=cds_srr(rdir)

it reports ERROR as following:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
??? Invalid MEX-file '/usr/local/apps/cadence/spectre/current/tools/spectre/matlab/cds_innersrr.mexglx':
/usr/local/apps/cadence/spectre/current/tools/spectre/matlab/cds_innersrr.mexglx: undefined symbol:
mxCreateScalarDouble.

Error in ==> cds_srr at 16
sig = cds_innersrr(dirname);
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I can only find one MEX file in the package for 32bit, that is cds_innersrr.mexglx, all the others are .m files.

"cds_srr" function use "cds_innersrr.mexglx" file, but looks like something wrong with it.
I have no idea how to open .mexglx file and how to check the problem. I appreciate your
help, Thank you!

  • Hi Candygg,

    The trouble is that you are using too old a version of MMSIM with a brand new version of Matlab.

    This problem was caused by us using a grandfathered function (I think that's the terminology that the Mathworks use) in the toolbox which got removed in Matlab 2009b.

    You're using a version of MMSIM from 3 years ago (something like that), yet using Matlab from this year.

    The problem was fixed in MMSIM711 ISR9 in July 2009 so you'll need to use a version later than that - I'd suggest using MMSIM7.2 or the latest release MMSIM10.1 (there was a jump in the version numbers to catch up with the year - so MMSIM72 is the release before 10.1 which was released in the last few weeks).

    Regards,

  •  Thank you very much, Andrew! It is very helpful! Otherwise, I might waste lots of time trying to figure it out. 

    BTW: Please ignore the email sent by me on "The Designer's Guide Community".

  • Hello,

    i'm working with MMSIM 7.2 and Matlab2010a (7.10.0) and Virtuoso 6.1.4.

    The toolbox works fine if i'm using in a Matlab script (inside ADE XL) without any cds_srr statements, for example:

    axlResult = 0; 

    or if i'm plotting some stuff (like the example in the documentation). But if i want to load a signal with the cds_srr function i got an error:

    Vi = cds_srr(psf, 'dc-dc', '/Vi');
    ??? Undefined function or method 'cds_innersrr' for input arguments of type 'char'.

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

    I cant find this function, there is only a mex file in the folder tools/spectre/matlab (cds_innersrr.mexglx)

     What can i do? Did i forget something?

     Thanks for your help!

     

  • I suspect that you have run into the issue described in the following solution (if it does not resolve your problem, please file a Service Request with Cadence Customer Support support.cadence.com ):

    http://support.cadence.com/wps/mypoc/cos?uri=deeplinkmin:ViewSolution;solutionNumber=11500586

    Make sure your <path>/tools/lib/64bit 
    is at the beginning of the LD_LIBRARY_PATH 
     
    best regards,
    Tawna

  • I'd also suggest that you try running matlab standalone and then calling cds_srr() interactively, and ensuring that works, before you start trying to use it in an ADE XL measurement. Did you set $LD_LIBRARY_PATH like I (and Tawna) suggested earlier? 

    Regards,

    Andrew.
