Subject

[Documentation] for documentation errors.

Describe the bug

I would like to start from Hierarchical gate netlist DEF/LEF/.lib in openroad-flow-script environment.

Expected Behavior

Start from floorpan placemnet router to GDS out with Makfile. I may need to add config in Platform and Design also.

Environment

[WARNING] Your current OpenROAD version is outdated.
It is recommened to pull the latest changes.
If problem persists, file a github issue with the re-producible test case.

You can use CACHED_NETLIST

@maliberty
Seems document not updated here: https://openroad-flow-scripts.readthedocs.io/en/latest/user/FlowVariables.html#synthesis for CACHED_NETLIST usage.

Thank you. Can I see the CACHED_NETLIST usage documents? Also, If I can also use placed def for following router.

Here is an example of the usage:

OpenROAD-flow-scripts/flow/designs/gf12/ca53/config.mk

Line 7 in 26998c0

export CACHED_NETLIST = $(PLATFORM_DIR)/$(DESIGN_NAME)/rtl/ca53_cpu.v
You just point to a gate-level .v file.

For a placed DEF you'll need to skip a lot of flow steps. It would be easier to just write a small script to run those steps.
