Creat blockage from polygon?

blankman

Hi,

In virtuoso i'm wondering if its possible to create a routing blockage from a set of polygons? I have tried the auto feature however it only creates the boundary box of the selected set, not individual polygons.

Thanks in advance,

Brian.

  • Ramakrishnan,

    I'm using prog1 (not prog) because I want the return value of each branch in the case function to be the list of points (you'll see the return value is stored in the variable points). Because I need to retrieve the list of points from the temporary object and then delete it, I use prog1 - prog1 executes all the statements in order but the return value is the first statement executed (as opposed to the usual convention of the last thing executed). So here the prog1 returns the list of points and then deletes the object from which it had retrieved the list of points. It avoids needing to use another variable - of course, I could have moved all the points= assignments inside the case statement but I'd already written the part which handled rect and polygon and then thought I probably should add path and pathSeg for completeness.

    Regards,

    Andrew.
