reading simulation results from cadence to matlab/ cds_innersrr

nevinalex1234

Hi

I am using MATLAB 2009a/2012a and MMSIM 10.11 and cadence virtuoso IC6.1.5.500.11  

I build a small low pass filter and ran the simulation in ADE and tried to read using MATLAB Spectre Toolbox. Its not working.

The error is attached as follows. I have referred to Matlabspectre.pdf and set the appropriate environments in matlab. Dont know why?

mydir =

/home/njacob2/simulation/design1_rcresponse/spectre/schematic/psf

>> nevin=cds_srr('mydir')
??? Undefined function or method 'cds_innersrr' for input arguments of
type 'char'.

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

  • env | grep MATLAB returns nothing

    asf24lin2-28: env | grep LD_LIBRARY
    LD_LIBRARY_PATH=/cad/adi/apps/cliosoft/sos/linux_5/6.23.p3/lib/64bit:/cad/adi/apps/cliosoft/sos/linux_5/6.23.p3/lib:/usr/lib:/usr/libexec:/lib:/usr/lib/X12:/cad/adi/apps/gnu/linux/x86_64/5/lib:/cad/adi/apps/gnu/linux/x86_64/5/lib64
    ADIM_APPEND_TRACKER=MANPATH|LM_LICENSE_FILE|newPATH|CDSLMD_LICENSE_FILE|LD_LIBRARY_PATH|PERL5LIB|INFOPATH|PYTHONPATH

    matlab -n same results as earlier (shows version)

  •  Ah, it's possible you might be using a too old version of spectre - in the early MMSIM10.1 versions it had an issue with compiler compatibility. What does "spectre -W" return?

     I would also expect you to have MATLABPATH set - otherwise it won't find cds_srr (it needs to be set to <MMSIMinstDir>/tools/spectre/matlab if using 32bit Matlab).

    Andrew.

  • Where's your working directory? (what does "pwd" say?). I assume you're trying to run this from your workspace.

    You've not copied cds_srr.m into your user area?

    Have you tried setting MATLABPATH to the place I mentioned? That's what you're supposed to do.

    Andrew.

  •  By the way, that version should be new enough not to have the compiler incompatibility.

    Andrew.

  • Yes i ran that from workspace.

    Do i need to copy that cds_srr.m ? I entered the matlab environment so it must automatically read it write ?

    cds_srr is getting correctly initiated in matlab

      but its cds_innersrr thats propping up the issue. In fact there is no pure cds_innersrr.m function in the path. there is only a cds_innersrr.mexglx 

    Is it why the error below props up

    >> cds_srr
    >> help cds_srr
       sig = cds_srr(dirname, dataset, signame, verbose)
       dirname: the path of psf or stt2 results
       dataset: the dataset name in the results, when only 'result dir' give out, the command will return all dataset names.
       signame: the name of signal in the dataset, the command will return all signal names in the dataset,
                when this parameter unset.

  • No, you don't need to copy it - I was wondering whether you had - I can't see how it is being found if MATLABPATH is not being set. IOt won't find cds_innersrr.mexglx unless MATLABPATH is set.

    Once matlab has started, can you type "path" and then post what it returns.

  • Looks as if MATLABPATH is indeed set.

    If you do Help->About in matlab, can you do a screenshot (using ksnapshot say) of the popup and post that (use the Options tab at the top of the Reply to an Existing Message section on the form)?
