| Is it possible to run `estimate_parasitics -global_routing` on a post-global_route design that's been loaded via the `read_db` command? As in, `global_route` has been run on the design before it was saved with `write_db`, but `global_route` has not been run in this current OpenROAD session. I keep getting this error: | |
| ``` | |
| >>> read_db post_global_route | |
| >>> estimate_parasitics -global_routing | |
| [ERROR RSZ-0005] Run global_route before estimating parasitics for global routing. | |
| ``` | |

| @eder-matheus I thought this was possible. Please comment | |

| Are you using a very old version of OR for this? The guides should be saved in the db. | |

| OR improves a lot over time so it is a good practice to test with a current version when you find a problem. | |
