Title: Calibre PEX warnings WARNING: Could not find property ID for "sa".
Post by mvaibhav on Jan 13^th, 2009, 7:20am

Hi,

When I run Calibre PEX on my design in IBM process, it creates the Calibre view but gives warnings like:

WARNING: Could not find property ID for "sa".

"sa" is a property of the FETs used in the design. So, basically, it's not evaluating this parameter which is important for simulations. In the extracted netlist I see some default values of sa.

Can anyone tell me what's wrong?
Thanks.
Regards,
vaibhav

if you're getting your kits/fab support through mosis then try asking on their message board: http://tech.groups.yahoo.com/group/MOSIS_Users_Group/

i've seen notices in my output log such as

`sa1' is not specified. `sa' is used.
`sb1' is not specified. `sb' is used.

but never thougth much of them. im working with ibm cmos8rf-dm 130nm kit btw

Hi,
I'm also using the same kit IBM 8RF-DM 130nm. In your case, at least it is using the property, in my case I think it's totally ignoring it. I ask Mosis support but they never encountered this problem. I'll try on Mosis yahoogroups.

Thanks.

What version of the kit are you using? Every time the admin updates the kit, the user has to do some changes to his/her .cdsinit, .cdsenv, .simrc, display.drf (or overwrite local copies with the ones in /<version>/IBM_PDK/cmrf8sf/<subversion>/cdslib/examples/). These files refer to full paths, even if you create the rel symbolic link. What I did is edit the files to point to rel so that I don't have to overwrite them everytime. If cadence is looking for files in different releases of the kit that might screw things up, so make sure everything is pointing to the latest version of your kit. Not sure if this will solve your problem, but its worth a shot.
