cv = geGetEditCellView()

vreDeleteSignalRouting(cv "stdCell" "nr")

The following example specifies options in batch mode for the device-level routing, and then performs signal routing deletion.

cv = geGetEditCellView()

handle = vreGetHandle(cv 'device 'gbr)

vreSetOptions(handle '(nil route_nets "All" route_netsWithin "PR boundary" route_routedLoc "Current Cellview"))

vreDeleteSignalRouting(cv 'device 'gbr)
