Coordinates of the Gates of MOS Devices on the Layout

baltacican

Hello,


I would like to get the coordinates of the gates of all of the MOS devices on the layout with their corresponding paths in the top level schematic view. I need to have this data in a text document listed for all devices. Is that possible? If yes where and how I can get it?

I am using Assura LVS and QRC. The version of Virtuoso is 6.1.5.

Note: I get this information on av_extracted view when I select a device and look at its properties by pressing "Q". It looks like this:

Name: PG_Mer_PN|PG_Mer_N|Propagate|N1_4__rcx

Origin X: 1.51

Origin Y: 6.87

However, I cannot do this for each device (there are more than 5000 devices on my layout), therefore I need a text file summary.


Many thanks in advance.

Best regards,

Can

  • Can,

    You could do something like this:

    out=outfile("./report.txt")
    matchingMOS=list("nmos" "pmos") ; whatever the device names you want to find
    foreach(inst geGetEditCellView()~>instances
      when(member(inst~>cellName matchingMOS)
        fprintf(out "%s %g %g\n" inst~>name xCoord(inst~>xy) yCoord(inst~>xy))
      )
    )
    close(out)

    Regards,

    Andrew.
