Working with DC sweeps and OP

analogdesign

 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.

  •  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.
