    Working with DC sweeps and OP Reply

     Hello sir,

                  In  DC sweep (65nm technology)  I saved the operating points by including M0.m1:oppoint  in x.scs file. I am not able to plot the small signal parameters from calculator, but the same parameters i can plot from result browser. I hope i am clear. can u please respond.

    You can send the "signal" for the operating point parameter from the results browser to the calculator - then you can post-process it however you like. 

    By the way, the previous post in this thread mentioned the forum guidelines, which suggest you don't post on the end of an old thread, and also suggest that you state the version of the software that you're using - with that I would have been able to advise how to send the result to the calculator (it could be three different ways, depending on the version you're using - with 5141 it would be good to know if using AWD or wavescan)

    regards,

    Andrew

     Hello sir,

                   sorry for my delay in responding. I am working on virtuoso 6.1.3, in ADE XL environment. And i am using wavescan.

                   when i take the signal in calculator it looks like getdata("M1/m1:ids" ?result "dc-dc"). When i try to plot the signal 

                   from calculator i get the following message in icfb window

                   expression evalution failed: expression evalutes to nil

                   Moreover i save operating points in DC sweep using save M0.m1:all

    I've sorted out all your separate threads and posts in multiple forums, and separated it from the original (old) post. Please read the forum guidelines.

    Did you try using getData("M0.m1:ids" ?result "dc") ?

    Regards,

    Andrew.

     Hai sir,

               Thanks for your reply. I tried your suggestion.  Didn't work in calculator, but the same thing i tried in the script. 

    ocnScript generated from ADE XL environment

    selectResult('dc)
    ocnxlOutputTerminal( "/M0/d" ?plot t ?save t)
    ocnxlOutputExpr( "getData(\"M0.m1:gm\" ?result \"dc-dc\")" ?plot t ?save t)
    ocnxlOutputExpr( "getData(\"M0.m1:gds\" ?result \"dc-dc\")" ?plot t ?save t)
    ocnxlOutputExpr( "(getData(\"M0.m1:gm\" ?result \"dc-dc\") / getData(\"M0.m1:gds\" ?result \"dc-dc\"))" ?plot t ?save t)
    ocnxlEndTest() ; "65nm_design:65_amplifier:1"

    Problem is the graph pop's up with all the plots and disappears. I was tryig to solve the issue. I am very new to ocean script. can you please suggest me the solution to sort out the issue.
