Can not open OA library

dipayan

Hi all, I am new to Cadence digital implementation system. I have been using this package for a few days and I am getting these error messages quite frequently.

**ERROR: (ENCOAX-503):  Can not open OA library 'TECH_C35B4'. Make sure the library exists on disk and its entry is present correctly in the library definition file.
**ERROR: (ENCOAX-503):  Can not open OA library 'TECH_C35B4'. Make sure the library exists on disk and its entry is present correctly in the library definition file.

I used TECH_C35B4 from AMS and I am sure I wrote the correct path to the location of the technology files in the start-up script. Can anyone please tell me why I am getting this error message.

 Also, when I am not able to save my design as an open access database for some reason. I write a GDSII file and I am able to stream in the design in Virtuoso. I can see the layout with the standard cells, however, I don't see an accompanying schematic. Am I missing anything, is there something extra I need to do to make sure I am also able to stream the schematic?

 Any help on these issues will be really appreciated. Thanks very much. I have a chip deadline soon.

  • So, you did use "encounter -libDefFile  fileA ...." when you start your FE, right?   and also, inside the file "fileA", you should have lines like:

    DEFINE TECH_C35B4  {the full path to the location of TECH_C35B4 library}

    Also, if you have similar line for your design library inside the library definition file, the "saveOaDesign libName cellName viewName" command should allow you to save your result into your design library in OA format as long as the library is writable by you.

     I used to use verilog in (File->Import->Verilog") to get the final verilog netlist into Virtuoso to create schematic.

     Hope it help!
