QRC tch file

diablo

 There are 3 QRC techfile , typ, bst and wst. Is there a way to read all these 3 QRC techfile using set rda_Input(ui_qxtech_file) and use them as suitable in different analysis view? 

For example, while doing MMMC analysis, can we do something like this

 set_analysis_view -setup wosrt -hold best
extractRC using whichever QRC tch file is appropriate (not sure how to tell the tool which QRC tch file to use)

then timeDesign to get report

  • If you're doing MMMC, then your analysis views were set up with the create_analysis_view command which included a -delay_corner option. The delay corners are setup up with the create_delay_corner command which has a -rc_corner option. Finally, the create_rc_corner command is what points to the QRC tech files:

    create_rc_corner -name worst \
                    -cap_table "worst.CapTbl" \
                    -T 125 \
                    -qx_tech_file "worst.tch"

    Having said that, extractRC is the built-in FE extraction which uses cap tables. If you want to use QRC for extraction, you'll need to use runQRC. QRC will then be run for all corners referenced by your active views.

    So, just make sure you've got everything set up correctly in your MMMC commands, and you're good to go! (When using MMMC, it's the data in the MMMC commands that matters, not what's in the .conf file.)
