How to open schematic/layout cell-view in a window automatically at start-up?

Sheppie

Hi all,

This may sound to trivial to ask here, but I have spend way too much time looking for the solution, and no luck...

All I want to do is to tell Virtuoso that it should open a specific schematic or layout cell-view at launch in a window, so I don't have to do anything.

As far as I know of, there's no such parameter/argument I can pass on to Viruoso at launch.

Possible solution could be that in my personal cdsinit file (which is in our set-up loaded automatically at the end, after literally everything else has been loaded) I tell Virtuoso to open a particular cell-view.

dbopenCellViewByType opens it in memory, not in a window. How would I open it in a window?

Any suggestion is greatly appreciated. Many thanks in advance.

With kind regards,

Sjoerd

    Hi Sjoerd,

    You could (if it's a layout or schematic window - this is probably not reliable with some of the newer applications) just open it interactively once, then do Options->Save Session in the CIW. Then next time you use the file that was saved:

    virtuoso -restore cdsSession.save

    If you look inside, it's using deOpen - you could use either deOpen or probably the geOpen function is going to be a simpler function to use. The rest of the stuff in there is to resize the window and zoom in to the last zoom position, which you may not need.

    So it's probably as simple as creating a wrapper script around virtuoso which takes the lib/cell/view, creates a temporary SKILL script using geOpen(?lib "libName" ?cell "cellName" ?view "viewName" ?mode "a") and then uses "virtuoso -restore tempSKILLscript.il" to launch it.

    Hi Andrew,

    Thank you for your suggestions, and this sounds like the solution I hoped would be there. I'm already using a (personal) wrapper script to launch Virtuoso (amongst others: it copies my version of the .cadence directory over the one we get through the project set-up) so it's easy to add this to this script. Will try this tomorrow and will let you know when I get this to work.

    Once again, thanks a lot.

    With kind regards,

    Sjoerd
