slow vias arrays

ascott

Is there a way to tell the tool to quit trying to draw all the vias in my array as I copy or move them?

If I create a large array say 1000x 12, then try to copy it, the layout hangs (assuming to draw it) for a long time.

It makes working with large arrays very time consuming.

  • Which IC sub-version are you using? I don't see this behaviour in current versions - it's very fast for me.

    You can turn off the drawing during copy/move by using hiGetCurrentWindow()~>trueColorDrag=nil - normally that's not something I see people needing to do these days.

    I am using version IC6.1.8-64b.500.28. I noticed it happens when I am somewhat zoomed out.

    In the image the white outline is the via array I am trying to copy. The yellow outline is the copy. The dot in the red circle is my cursor waiting for my screen to come back to me. That array is 1250 x 11. I tried turning off update connectivity information when design is modified and it didn't help. I am working over a network...Texas to Arizona. Could that be the problem? Only happens with large vias though. I will try what you suggested.

    By "via array" do you mean it's a single via with the number of cuts set to 1250 rows and 11 columns?

    What are you using for the remote display over the network? VNC? Exceed Turbo X? Something else? I suspect this is the root cause, so I'd like to understand what you're using (before worrying about network speeds/latency too which might also have an influence here).

    Hi Andrew,

    Yes that is what I mean by "via array". I use Exceed TurboX to connect. I can choose a machine in Arizona from a list to connect to. I am going to ask about which machines have better processing and memory. The problem also is several people are on each machine. I am also going to ask another layout designer in San Jose if she is seeing this. No worries Andrew, I just thought there might be something in Virtuoso that I could turn on or off that would help this lag out.
