Parameter empty when using cds_srr function

Hi,

 I have a problem in reading the simulation results using Matlab. The problem is that when I am trying to read multiple parameters, the first one i read it correct but after that all parameters returns zero in value.  The Matlab code i am using is the following:

clear

addpath /opt/cadence/installs/MMSIM131/tools.lnx86/spectre/matlab

simpath=sprintf('/home/malhawari/simulation/boost_conv/spectre/schematic/psf');

datalist=cds_srr(simpath);

vd = cds_srr(simpath, 'tran-tran', 'vd');

vg = cds_srr(simpath, 'tran-tran', 'vg');

The result is the following:

>> datalist=cds_srr(simpath);

PSFversion: 1.00

tran-tran (tran).

finalTimeOP-info (info).

modelParameter-info (info).

element-info (info).

outputParameter-info (info).

designParamVals-info (info).

primitives-info.primitives (info.primitives).

subckts-info.subckts (info.subckts).

variables (design_variables). 

vd = 

    info: {'V'  'V'  'time'  's'}

    time: [7607x1 double]

       V: [7607x1 double] 

 vg = 

    info: {'V'  'V'  'time'  's'}

    time: 0

       V: 0

 Now if i flip the order of the vd and vg in the Matlab script where i read first vg and then vd i get the following

>> vg

vg = 

    info: {'V'  'V'  'time'  's'}

    time: [7607x1 double]

       V: [7607x1 double] 

 vd = 

    info: {'V'  'V'  'time'  's'}

    time: 0

       V: NaN

This confirms the problem of reading only the first parameter in its correct way while other parameters are zero.

 BTW I am using MMSIM131 and IC616, also i tried MMSIM121 and IC615 but i got the same results!

Thank you in advance for your help!

Regards
