#92 CVC: Incorporated CVC into openlane/flow.tcl Pull request opened by d-m-bailey This change enables CVC to run on the abstract netlist extracted from

maglef

cells. Currently, CVC on device level extracted netlists is not supported. 1. Create the appropriate CVC directories in

scripts/tcl_commands/all.tcl

2. Copy the abstract spice file to

*.lef.spice

(change to

run_magic_export_spice

in

scripts/tcl_commands/magic.tcl

3. Added

run_lef_cvc

to the

scripts/tcl_commands/lvs.tcl

(might be better to add to a separate file, but I didn't know how to setup the tcl library) 4. Call

run_lef_cvc

from

flow.tcl

5.

run_lef_cvc

creates a power definition file from the verilog file used for LVS and merges the cdl library with the

*lef.spice

file. 6. Model definitions are in

scripts/cvc.sky130.models

7. CVC parameters are in

scripts/cvcrc.sky130

Probably want to add error reporting. From the CVC log file the

CVC: Total:

line shows the number of errors.

CVC: Total: 0

Digital design will most likely have no false errors. Analog designs may have false errors that we can deal with later. efabless/openlane
