Error while streaming GDS file into Virtuoso

medeepak

Hi

I am new to Cadence tools. I used a synthesized verilog netlist of a MAC unit to generate its GDS files. Reference libraries used were NCSU AMI 06 TechLib and OSU AMI 05 libraries. After generating the GDS file when i try to stream it into Virtuoso it shows the following error

 

the referenced cell "BUFX4" was not found. The OpenAccess design data was created for this cell without any reference. Ensure that the referenced cell exists and the Lib is defined in the library definition fil.

 

But the definition for BUFX4 exists in the library though it is protected (i am not able to open it. And this error goes on for 20 similar mosules all of which have definitions in the library and Lib file.

Can anyone tell me what mistake i may be doing

_________

I tried to save my GDS file in Encounter as an OA file (inside a new library with NCSU AMI 06 tech file attached to it). When i do i get the following error

Cannot bind master OSU_stdcells_ami05/FILL/abstrac!

Unable to find OA layer for metal1 layer 'Encounter'. Check technology data associated with design

This error goes on for other metal layers  as well

Please help me

I use Encounter version 9.12 and Virtuoso version IC 6.1 

please tell me if had left any information

 

regards

  • Hi deepak

    When streaming in the gds file, would you please try setting "OSU_stdcells_ami05" as the reference library in the stream-in form? My guess is that when the gds file was exported from Encounter, it was not merged with the standard cell gds and hence only references and not the actual standard cells are present in the final gds file.

    Best regards
