Check LVS for Pcell

It looks as if you're loading the code to create the pcell and the CDF again (from the libInit.il in the library?). You do not need to do this. Once the CDF has been created it is stored in the cell's data.dm and once a PCell has been created, the code is stored in the cellView itself.

The only things that need to be loaded each time are any additional functions that are used within CDF callbacks or are called from within the body of the pcDefinePCell call - the code that forms the body is stored in the cellView, but any user-defined functions called from within the body are not.

Because you're trying to redefine the CDF and pcell each time, you either might have permission problems are be trying to create them in an executable that doesn't have all the necessarily functionality available.

By the way, sending me a friendship request with the same question is not a way to get an answer to a question. I don't accept friendship requests in the forums unless I genuinely know the person well or have explicitly asked somebody to in order to be able to send some direct info to me; I cannot answer direct questions from anyone the world over because I don't have the bandwidth and it rather defeats the point of having a community forum.

Hi Andrew, 

Thank for your help. These errors has gone. But have another error, below: 

"*Error* Cell: res in library: PDK is missing a simInfo section in it's CDF for the current simulator."

Have you any ideal for this error?

Looking forward from you soon, 

This means that whilst you might have defined CDF for the component res in library PDK, you've not defined the simulation information (simInfo) for the simulator/netlister that you're using. This is needed to tell the netlister how to netlist the component - which terminal order is needed, which parameters need to be netlisted, and so on.

Regards,

Andrew.

Thank you so much, Andrew

Have you a nice day !

Hi Andrew,

I have another issue, when I run LVS. I have some errors, below:

".......

LVS completed. NOT COMPARED. See report file: example.lvs.report

LVS completed. CPU TIME = 0 REAL TIME = 0 LVHEAP = 67/91/91 MALLOC = 59/59/59 ELAPSED TIME = 0

ERROR: Corresponding cells could not be identified.

ERROR: Nothing in layout.

*** Calibre finished with Exit Code: 4 *** "

I have researched in cadence forums and I know that I have not created any pin. So, I use a function to create pins, I show below:

minus = rodCreatePath(
?layer "M1"
?cvId pcCellView
?width w
?pts list(caar(contactLeft~>dbId~>bBox):
(abs(abs(cadadr(contactLeft~>dbId~>bBox))- abs(cadar(contactLeft~>dbId~>bBox)))/2 + cadar(contactLeft~>dbId~>bBox))
caadr(contactLeft~>dbId~>bBox):
(abs(abs(cadadr(contactLeft~>dbId~>bBox))- abs(cadar(contactLeft~>dbId~>bBox)))/2 + cadar(contactLeft~>dbId~>bBox)))
?pin t
?pinLabel t
?pinLabelLayer list("M1" "pin")
?pinLabelHeight 0.5
?termName "MINUS"
?termIOType "inputOutput"
)

But  the result is not changed. I do not why. May I wrong, am I ?. Would you help me ?
Thankyou 

I can't help you with a Calibre problem (it's a Mentor Graphics tool that I don't have access to) and anyway I don't have  your data either. The message "ERROR: Nothing in layout" is a bit suspicious though - not sure it's anything to do with not having pins. I suggest you read the entire log file and maybe contact Mentor about it.

Regards,

Andrew.

You need to change the CDF Type to "Base" rather than "Effective" before making the changes. Otherwise the changes are in memory only.

Regards,

Andrew.
