    MATLAB-spectre interface reading conjugate AC simulation value Reply

     Dear All,

    I used the Matlab-spectre interface commmand to draw AC simulation result of SPECTRE in MATLAB.

    The comand I used are belw:-

    resdir = '/home/..../simulation/TB_TIA_INPUT_IMPEDANCE_TEST/spectre/schematic/psf';
    signals=cds_srr(resdir,'ac-ac');
    Vod=cds_srr(resdir,'ac-ac','Vod');

    It looks like in MATLAB I am getting the conjugate of Vod. This I learned when I plotted 'Vod' phase and Magnitude in spectre Wave-scan.

    Can anybody please tell whay it is happening so.

    Kind Regards

    Looks like a bug. I filed CCR  1034997 for this. You might want to contact customer support and request that a duplicate bug is filed for you so that you can track when the fix is available.

    Regards,

    Andrew.

    This should be fixed in MMSIM11.1 ISR14, which is currently due to be available on downloads.cadence.com around the 23rd August.

    Regards,

    Andrew.
