Hi,
I am using SOC Encounter for the first time. I have done the placement
and routing of a circuit using Encounter. I want the congestion
statistics of the design after the detailed routing is complete.
On reading the User Guide, I understand that dumpCongestArea command
gives the congestion statistics after the trial route or global route.
I used the command after trial route to get the congestion statistics.
It showed me negative values of remaining tracks. Then, I did detailed
routing and used the dumpCongestArea command. The two files have the
same data. But, if i try exporting the gds layout and do a post layout
simulation on the circuit, it produces the correct output. Hence, I
concluded that the circuit has been routed properly. So, there cannot
be negative values of remaining tracks after detailed routing.
Can someone explain me the procedure to get the congestion data of the
design after detailed routing?
Thank you.
