| I have run the following script:
|
| ```
|
| read_lef ispd19_test6.input.lef
|
| read_def ispd19_test6.input.def
|
| set thread_count 8
|
| global_route
|
| detailed_route
|
| write_db route.db
|
| report wns
|
| >> wns 0
|
| report tns
|
| >> tns 0
|
| report worst_slack
|
| >> worst slack INF
|
| ```
|
| Did anything go wrong? How can I get correct metrics? Thanks a lot! |

| Do estimate parasitic and then report the metrics. Refer here: https://github.com/The-OpenROAD-Project/OpenROAD/blob/master/test/flow.tcl#L264-L280 @xiaosinju |

| This is a routing test case and has no timing information (no .lib or .sdc). What are you trying to accomplish? |
