plotting gm of DC simulation without file creation

robert 21

Hello  i am trying to plot gm of DC simulation by showing the  gm in the result browser


The way i found  to do it is by  creating a file  with a single line  "SAVE M0:all" save it as scs file and put it as a stimulus file as shown bellow.

However i am running my projects from a very restricted LINUX server i dont have the ability to create files or change directories..(i only can run cadence virtuoso)

Is there an alternative  way to create a gm plot without creating a file?
Thanks

  • In numerous posts on this forum, I suggest using "Outputs->To be saved->Select OP Parameters" for this (this was added in an IC616 hot fix, so it's been there for a very long time now). No need to use an external file. You can pick the component and tell it to save "gm" or "oppoint" to save them all. You can also access the results using the "ot" button (for transient operating point) or "os" for DC sweep operating point in the calculator, or can continue to use the results browser.

    If you search for "Select OP Parameters" (with quotation marks included) in the forums you'll find other references (not sure whether I've ever given a screen shot or a detailed step-by-step description, but then again it's pretty easy to use.
