[SOLVED] RC Extraction

nitin mukesh · Dec 9, 2022

Hey Everyone,

I am using Cadence and for RC extraction I am using ASSURA Quantus.

1. We can run the RC extraction for the .sp (spice) format.

2. But whenever we try to run the av_extracted view, we get an error stating:

*Error* def: given function is internal and cannot be redefined - round2
*Error* load: error while loading file - "/nfs-cadenceshare/afs/vlsi_iitbhilai/PDKs/umcoa/L180/process/UMC_MM_RF_CO1/UMC_18_CMOS/.load/pcell.180" at line 0

*ERROR* Terminal B on cellview (gpdk045 mimcap ivpcell) is not defined on device (mimcap#20ivpcell#20) in the extraction rules

The error log file & assura quantus setup screenshot has been attached.

I am not able to understand when I am using TSMC 65 Library why it is looking in for other libraries.

Where I am going wrong?

I believe PDK is not compatible with Cadence Assura Quantus.

You are mixing gpdk90, gpdk045, umc180 and mentions tsmc65 and asking what is wrong?

I understand that but I am not understanding where it is getting mixed as the assura tech file, I am using is TSMC65.

Do you have any idea why it is considering other PDKs ?

Dominik Przyborowski · Dec 10, 2022

It is clearly stated in the log file.
In your design are devices from 4 different processes, while assura is configured for 5th different process. Clean your mess.

I also thought the same.

But I have created a library where I have attached tsmc65 and used tsmc 65 nmos in schematic and as well as layout.

I have used a single transistor of tsmc 65 where and why the quantus QRC is checking for other librariies is the quetion.

Any idea how can i check that.

PS: LVS is running fine for the same assura tech file.

Dominik Przyborowski · Dec 11, 2022

What is inside your pvtech file?
How are you creating svdb?
How is ccl looking like?

The above problem is solved by removing the library which was clashing.
