What is the correct usage of the variable CURRENT_STEP in the openlane Makefile? It seems like this allows you to re-run starting from a step, but it always deletes the run directory for me...

The `OPENLANE_BASIC_COMMAND` in `openlane/Makefile` uses the `-overwrite` flag that causes the run directory to be deleted before the next run. If you start the docker container manually, you can call call `flow.tcl` step-by-step, e.g. using `-from` or `-to` , or continuing after an interruption. You can also place an `interactive.tcl` script in your project's openlane directory.

Thanks. Hm, I don't want to run manually, so maybe I will just hack that flag out.

Seems like they should disable -overwrite if you pass CURRENT_STEP

<@U02G1ME9XCL> How do you start the docker container manually? If I use openlane "make mount" it doesn't mount the caravel user project directory

(I could export that volume manually starting docker but this is getting too interactive)

I just made the new target in the Makefile where I replaced the docker command line with a simple bash

Yeah, that's what they have in openlane. Odd that they don't have these already.

I'm trying to minimize my differences just for merging/maintenance reasons
