PVS-QRC vs Assura-QRC

magal

Hi,

I'm trying to migrate from Assura extraction to PVS. Tool versions:

IC6.1.7

Assura41.6

PVS191

EXT191

I have LVS decks which were supplied by the fab (e.g. TSMC65nm GP), and both PVS and Assura LVS work fine (i.e. clean cell, no funny log errors).

However, when running QRC with the Assura database it runs fine (again, no funny errors, result makes sense etc) but PVS-QRC terminates with the following error:

"There was no library cell mapping file (extview.trp (V2) or icellmapfile.yaml), or alternatively the extview"

What is happenning? I did some reading and it seems like the fab should give me either of the missing files. But then - how is Assura-QRC working? And if it does - Is there a way to retreive the missing information from the Assura deck files?

I'm in contact with the fab but this might be lengthy. In the meantime any help will be much appreciated.

Thanks!

    Please contact customer support. We can't really provide technology-specific advice in a public forum without breaking the NDA with the foundry, so you really need to do this via customer support.

    Thanks, Andrew. I found a workaround to create this file. QRC now runs, but differently than Assura database it does not produce the layout -like graphics (parasitic elements are there though).

    Since Assura works, and what I really need is QRC extracted views, I'll keep using Assura until I get some response from our vendor. I might also contact Cadence support, but I'm not sure it's worth the effort.

    Thanks anyways!
