How to follow a wire in the layout?

MohsenShah

I have a mixed-mode layout designed by someone else and want to track the digital clock routing path in the Layout GXL (metal layer changes in the path). I open the layout VIA the schematic window but when I click on the wire, it doesn't highlight the corresponding metals in the layout. Hence, I should follow them physically which is time consuming and prone to mistakes. Is there a straightforward way to follow a track in the layout (e.g. highlighting the selected node like what we do in schematic view/net highlighting).

If not available, can I manually highlight a metal path in the layout such that I can go back and forth to double check the path I was following?

I am using the following versions and sub-versions:

virtuoso version 6.1.6-64b

sub-version IC6.1.6-64b.500.6

Thanks!

  • Maybe the layout wasn't created with Layout XL/GXL and so doesn't have connectivity information? Perhaps you need to do Connectivity->Update Components and nets?

    Otherwise you could use Connectivity->Mark Net (apologies, the menus might be slightly different - I'm writing this from memory rather than having checked).

    Regards,

    Andrew, thanks for your response.

    I checked the Connectivity->Mark with another layout I drew. It works properly and is exactly what I wanted. However, in the current layout it is not working because I cannot select metal layers (selection for all layers is enabled for all layers). It seems that they 'grouped" or "locked" them in anyway. I inquire them for this problem. Thanks again!
