Flightlines in Layout XL

pham777

When I do top level layout in XL and try to show all incomplete nets, I do see flightlines come up but not ALL OF THEM. I did connectivity->update->extract layout, but it did not help. I noticed that when I move some of the sub blocks off a little bit, some more additional flightlines coming up, then when I made some routing at the not-shown flight lines, at these places, flightlines start showing up again.

At the end, no matter what I do, some of incomplete nets never show flightlines, that why I miss a lot of connections until I find out when I run LVS.

Does anyone have this problem before, and how do you get around this ?

I'm using cadence IC615.06.15.151

Thanks a lot,

HA

  • Hi HA,

    If the extractor has reached the maximum of opens then it won't create all the flightlines. You have as well a message in the CIW to tell you that the extractor has reached the maximum.

    Please look at the Options -> Layout XL -> Extraction -> Maximum number of open violations By Net, By CellView.

    You can try to increase the number to see if the flightlines are fully created.

    Thanks,

    Alex
