Pcell Evaluation Failed Issue

Muralidhar

Hi,

I have an issue, when I invoke the tool I am getting pcell Evaluation failed for all the cells coming from techlib.

I am working in 10 nm and tech lib is cmos10lpp.

What I did is I copied cmos10lpp folder from one path to another path (into my local) and I added my local path to cds.lib

Then I tried to invoke the virtuoso (V12.3-64.b) then if I tried to open the layouts all the cells pointing to cmos10lpp are getting pcell evaluation failed.

I re invoked the tool and attached the techlib also but same problem exists.

I opened the layout then  in the verify ---> Markers --> Explain and then clicked on the layout then it is saying

location: ("cmos10lpp" "egpfet_b" "layout")
reason:   ("eval" 0 t nil ("*Error* eval: undefined function" Secln10lpp_mosfet))

Can any one tell me the solution please.

    I don't know the specifics of that PDK, but the most likely explanation is that the cmos10lpp library contains a libInit.il file which attempts to load some supporting SKILL functions used within the pcells. I would expect that it is trying to load the code (maybe as SKILL files or encrypted SKILL files or a context file) in a location somewhere relative to the location of the library (e.g. ../skill or something like that). So when you've copied it to your local area, that path doesn't exist, so functions needed within the pcells haven't been loaded. 

    You should check the contents of the libInit.il (and also the structure of the PDK) to see if such a relative path exists, and you might need to create a symbolic link in your working dir to the "skill" directory (if that's what it is called) in the PDK hierarchy.

    Hope that helps. It's a bit of a guess without being to see the specifics.

    Regards,

    Andrew.
