how to overwrite veriloga code in cadence

black tea

Dear all,

I use one gain control which write by verilog-A code.  After I create the symbol for the code and use it for simulation, no matter what change i did for the code, there is no change for the gain control. For example, at first I set the gain is 100, save and create the symbol, then use it for simulation, but I find this gain isn't enough, I want to change the gain to 200, but when I change the gain number in verilog-A file and save. these still no change when I simulation. I create a new one for every change, it makes me crazy.......So I want to know how to overwrite the verilog-A code instead of  create a new one in cadence.

Thanks a lot,

kind Regards.

  • Either do Right Mouse->Open in the Library manager over the view, or File->Open->CellView in the CIW. This should bring up an editor. If it's an older version, it will bring up whatever editor you have configured (via the $EDITOR UNIX env var, or the editor SKILL variable), but if using IC616 ISR7 (I think) or later, there is a built-in editor in Virtuoso for these views.

    You need to save and exit the editor which is launched (if using a version before the built-in editor) to have Virtuoso detect the change and re-check the file for syntax and identify the inputs and outputs and also to mark the cellView as having been changed.
