Is there any faster way to get hierarhically tree report?

kbhow

Hi Expert,

I'm working on a big fullchip, and looking for a faster way to get the hierarhically tree summary report from "Top to Bottom". Currently, when i use File->sum from virtuoso layout, it took 18 hours to generate the report, which is too time consuming.

I wrote a simple skill script to recursively search hierarchically and print the report. This required more than 11 hours too. =<

Is there any ways that we can get/generate the hierachically report in faster way (<10 minutes? ). Will "Python" scripting solve this issue?

Your help is much appreciated. Thanks

    hi Andrew,

    Thanks for your fast response. =)

    Currently, i'm supporting many version of Virtuoso from IC514 to IC614, IC615 is yet to released.

    I was hoping that the traversing hierarhically work instantaneously, but it doesn't. It is still OK for smaller block such as core, but for fullchip, the time is totally failed.

    Do you have any advice that i can improve the run time?
