Error in Calibre LVS

srihari18

Hi i did my layout in cadence virtuoso and i had passed clean the DRC and LVS. Now when i run calibre DRC i am getting "metal density error". I was testing a layout design that was already fabricated and tested. This design had dummy metal layers to meet the density requirement but still the DRC error didn't clear. Having that aside i ran calibre LVS. I chose the option "Layout vs netlist" and had to include the "project.src.net" file. But i didn't have this file to include. Is there any step that i am missing. Could anyone pls tell me how to obtain this file??? I also chose the option "export from schematic" but when i run LVS i am getting the error "schematic export failed"

I later chose the option "Netlist extraction" and LVS generated a .sp file. I included this file and ran LVS under the "Layout vs netlist" option. Now i am getting the error "Nothing in layout", "nothing in source". Can anyone plsss help!!! Thank you :)

    This probably isn't the best forum for asking questions about Mentor Graphic's Calibre tool, since these forums are related to EDA tools from Cadence Design Systems - and Calibre is not (it's from Mentor Graphics).

    Of course, you might get an answer because there are probably plenty of folks here that use Calibre (not me though, because I don't have access to it).

    Kind Regards,

    Andrew
