cds_ff_mpt PDK?

Hi, rsashwinkumar and Andrew

I would like to ask if you confront with the problem that there are no "qrc_options.yaml" file while extracting RC via BAG.

As I use GUI  to extract, there are no problems. Therefore, I went to see bag_config.yaml to check what is going on. I found that there aren't existing "qrc_options.yaml" 

I use the same pdk(cds_ff_mpt) as you. 

If you have any instructions, please let me know.

here is my email address: rayyeh942@gmail.com

Appreciate

Sincerely

Daniel

I know nothing about this "BAG" (I had to do a Google search to figure out that this is the "Berkeley Analog Generator"). The missing file is not a file that is needed by our tools, so I assume it must be something to do with this BAG system. You should contact the maintainer of the repository (or use the Issues page on the GitHub project).

Andrew.

Dear Andrew,

Thanks for your rapidly reply. 

As for this file, I have already consulted with the maintainer of BAG, and he left a message as showed in the following picture.

He said since Cadence doesn't provide the extraction flow of the cds_ff_mpt; therefore, it is hard to set up "qrc_options.yaml", which is the artifact file written in python to let the BAG system run RC extraction automatically.

Could I ask about which PDK has provided the supported extraction flow?  Or which file is the "extraction flow" of the cds_ff_mpt downloaded from http://pdk.cadence.com.

Thanks a lot

Sincerely

Daniel

Hi Daniel,

I suspect the maintainer of BAG is talking about an old version of cds_ff_mpt. The 0.3 version didn't have Quantus QRC rules, but the 0.5 version (which is the currently available version on http://pdk.cadence.com )  does  have Quantus QRC rules set up:

UNIX> /bin/ls -R cds_ff_mpt_v_0.5/qrc
cds_ff_mpt_v_0.5/qrc:
best corner.defs typical worst

cds_ff_mpt_v_0.5/qrc/best:
RCXdspfINIT _p2lvsfile cds_ff_mpt_best.ict extview.trp lvsfile
RCXspiceINIT callProc.il compilation_cmd layer_setup qrcTechFile

cds_ff_mpt_v_0.5/qrc/typical:
RCXdspfINIT _p2lvsfile cds_ff_mpt_typical.ict extview.trp lvsfile
RCXspiceINIT callProc.il compilation_cmd layer_setup qrcTechFile

cds_ff_mpt_v_0.5/qrc/worst:
RCXdspfINIT _p2lvsfile cds_ff_mpt_worst.ict extview.trp lvsfile
RCXspiceINIT callProc.il compilation_cmd layer_setup qrcTechFile

Regards,

Andrew.

Dear Andrew,

I got you. I will provide this information to the maintainer and discuss it with him.

Thanks a lot. You save me lots of time!!
