Hi,

I have several sram macros in my design generated from memory compiler which cannot generate GDSII file. I streamin the design in Virtuoso and tried to run DRC but have this error:
Code: 
ERROR: Cell sram_1kb is referenced but not defined.

When I streamin in Virtuoso, there are warnings related to this macros:

Code: 
WARNING (XSTRM-267): The referenced cell "sram_1kb" was not found.The OpenAccess design 
data was created for this cell without any reference. Ensure that the referenced cell exists and library is 
defined in the cds.lib file.

Is it possible to do DRC without the layout of the sram? How other people do the DRC for this situation?

Thanks in advance.

You can black-box it by creating empty cell "sram_1kb".
 

How can I do that in SoC Encounter? What is the command we use to create black box?

Thank you.

While streaming in, there wil option to provide reference library..
Provide the library which contains "sram_1kb" in reference lib option..
 

Thank you for your reply. I don't have the reference library for the sram_1kb. It is generated from memory compiler given by the foundary. From the memory generator, I generate LEF files for place and route in Encounter. The memory compiler that I have cannot generate GDS and netlist files. That is the problem to import it in Virtuoso layout.

Thanks.
