How to make a iteration of all the VIAs in SOC Encounter database?

archive

Hi, all:

I am Roc Sun. Recently, I got a few problems.

One is how can I iterate all the via instances in SoC Encounter. I can find the command 'dbViaCellName' or something, but I can not find the way to get via instances. As you know, in SoC52, it 'split via' utility is not working. So, I want write my own version using database command.

The other is that, how can I get all the drc box coordinates, I mean the white boxes after we made a DRC check in SOC Encounter. I want to write this script in db commands.

Best Regard!

  • Perhaps the best way to get via instances is with the "editSelectVia" command. It has a lot of options for filtering that will hopefully enable you to get the vias you're interested in selected, and then you could iterate through the db pointers of the selected set with "dbForEachHeadSelPtr". You might also consider using the "editChangeVia" command to modify certain via instances. I'm not sure what you want to do with the via pointers once you've gotten them, so please do post back if additional building blocks would be helpful to you.

    I am not aware of a way to iterate through the drc boxes via TCL. In the past, when I've needed to do this, I've processed the text output of verifyGeometry to get the drc box coordinates. I realize this can be cumbersome, but hopefully this can be addressed with an enhancement to the tool in a future release.

    Hope this helps,
    Bob
