CDS_thru, LVS, new layer

samer1

I am using cadence ic616 and calibre for lvs/DRC/xRC. I added a new layer in the kit (IBM 65nm 10LPe). I want that layer to be shorted during LVS. I learnt that CDS_thru can help with that and I have been trying to add several views of the CDS_thru to my device representing that new layer but still the LVS is not working. It is showing the following error:

No matching ".SUBCKT" statement for "memr_hfox" at line 62 in file "/home/samer1/cmos65nm/TS_Form_prog.src.net"
Source could not be read

can someone help with that?

thanks

    This might be more of a Calibre question than a Virtuoso question, so you might be better advised asking this on a Mentor forum rather than a Cadence forum (since Calibre is a Siemens-Mentor product). The error message looks as if it's coming from Calibre...

    Regards,

    Andrew.

    I just had an extra question. LVS cannot find the SUBCKT for the device "memr_hfox" in the auCDL netlist. I assume when Calibre exports the auCDL of the schematic, it ignores the "memr_hfox" device or cannot find its definition. What I did from a cadence standpoint is, I added the auCdl view of the device in the viewlist (otherwise it was not running at all) and copied the spectre parameters in the CDF to auCdl (in the by simulator tab). I'm just wandering why Calibre cannot find the SUBCKT of the device. Do you think there is any cadence related issue that might be causing that?

    Thanks
