Is it possible to import and simulate in virtuoso without the exact GDS info of the layout??

Hello everyone,

For the standard cell library I was provided with, I have the following files:

1. .lib files(worst,best,typ etc.)  2. .v file (verilog description of the std cell library)  3. .lef file  4.  captable

With these files I was successfully able to do:

1. RTL synthesis (done by Genus) 2. PnR using innovus (including postroute optimization)

Now I want to import the design in virtuoso and run rc extraction, simulations etc. But I have no GDS file of the standard cells. Instead, I was given some phantom views (FRAM view, CEL view etc.) which are some sort of abstract views (please correct me if I am wrong) supported by  synopsys as I have come to learn and I do not have the tool. All I can generate is the GDS of the routing info from innovus. Now, please tell me how far I can go with these. 

I am still learning the tools. And I found out that it is possible to create abstract views of the standard cells using .lef file from innovus. 

I was wondering if it is possible to import and run simulation from virtuoso using these abstract views?

I still have no idea how the rc extraction can be done using this information. But while doing the PnR, innovus uses the RC extract information and optimizes thereby. So the information is available for innovus in .lib files and captables. Is it possbile to import this info to virtuoso in some way and run the simulations from there??


I should also add that I have the PDK using which the standard cells were created. But without the exact GDS information, will it be of any help??

Please correct me if I am missing something obvious. Any kind of help, suggestion will be very much appreciated. Thanks in advance.

    You can use OA based flow to take your design to virtuoso. 

    Refer to following article
