ocean XL

analogdesign

 Hai,

        I am very much new to oceanXL script.

        By using "save M1.m1:oppoint", i can't plot small signal parameters of MOS in ocean script.

        The expression willl appear as

        ocnxlOutputExpr( "getData("M1.m1:gm" ?result "dc-dc")" ?name "namegm" ?plot t ?save t).

        I would be thankful if anybody can post the solution for the above problem.

 Thanks,

 krishna

  •  Hai sir,

               Thanks for your reply. I tried to run the script with your suggestions. But still it is not working. Its a dc sweep.

               From the result browser signals can be plotted. I am attaching the script here.
