issue with make_cdb

gops over 13 years ago

Hope every one is doing fine with their designs.

Can someone please help me with the following issue.

I was trying to generate cdb files using .cdl model and .scs model.

My .cdl model contains the netlist for the cells(lvs netlist) and .scs model contains the transistors and their parameters. But when I tried to use make_cdb, I'm getting an error from the tool saying that the cell doesn't contains any transistors. I checked the cell, it is a clock mux cell and it contains the transistors and the transisor defenition is in the .scs file as well.

can someone help me sort out the issue. If you need the .cdl file and .scs model for the purpose I can upload it. Please let me know if anyone can help.

thanks

Can someone please help me to generate the .cdb file for "cell_r" in the attached .cdl file. I have also attached the spectre models for the transistors. Also i have attached the script file for make_cdb.

The files are also available with the support site of cadence (incase you don't want to extract the zip file I have uploaded here)

Hi Gops,
I'm no expert in this area, but it looks like your make_cdb.tcl script is not complete. Please check the "make_cdB Noise Characterizer User Guide", available at support.cadence.com. At the very least you are missing the .lib file. I'm not sure if this helps. Keep pushing the Service Request you filed, they should be able to get this working for you.
