When I tried to run DRC for 90nm process design in virtuoso layout suite I got a warning saying " cannot find rules file "divaDRC.rul" in techfile library "cmos090" and DRC failed. I dug up into the matter and came to know that there is no as such diva file for 90nm process however it has got support for DRC using calibre. Does anybody know how to set that up or how to solve this problem.
Thanks to all those who spent time suggesting solution to last posted problem.
I'm guessing from the techfile name, CMOS090, your foundry is ST. This process does not support DIVA, you have to use Calibre for DRC/LVS.
In reply to tkhan:
You are totally right about foundary name but how can I setup calibre properly for DRC/LVS because I already have tried it but it seems like I haven't set it properly.
In reply to affaq:
I've never used the PDK, we just have it installed on our network. In the /doc folder there is one pdf related to calibre, maybe you should read that.
There are 2 ways to run Calibre:
a. Export schematic as cdl netlist (ciw:File->Export->Cdl) and layout as gds (ciw:File->Export->Stream). Specify both inputs in the calibre drc/lvs control file and run in batch mode.
b. Run drc/lvs from within Virtuoso using Calibre menu. The basic steps to set up the "Calibre" menu in the layout editor are as follows. For help in troubleshooting the setup, I think you should contact Mentor Graphics because the menu SKILL file is provided by them. It is not from Cadence.
Add the following line to your cshrc file:setenv MGC_HOME <path-to-your-calibre-software>
Add the following commands to your .cdsinit file:=== IC5141 ===load( strcat( getShellEnvVar("MGC_HOME") "/shared/pkgs/icv/tools/queryskl/calibre.skl" ))
=== IC613 ===load( strcat( getShellEnvVar("MGC_HOME") "/shared/pkgs/icv/tools/queryskl/calibre.OA.skl" ))mgc_load_calibre_menu()
=== IC613 ===load( strcat( getShellEnvVar("MGC_HOME") "/shared/pkgs/icv/tools/queryskl/calibre.OA.skl" ))
