Are all openlane configuration variables listed here: https://github.com/efabless/openlane/tree/master/configuration ?

@Dejan Petkovic: Some are PDK specific and are listed in

sky130A/libs.tech/openlane

. Or do you mean the documentation?

@Amr Gouhar I was mainly thinking about the ones used in

config.tcl

. Sometimes, somebody on slack mentions a variable I have not seen described in the link above. For example, now I have heard about MAGIC_DISABLE_HIER_GDS and earlier there was no PL_RANDOM_GLB_PLACEMENT and ROUTING_STRATEGY (probably deprecated). Also, we have used MAGIC_WRITE_FULL_LEF for caravel, I don't see it either, etc.

@Dejan Petkovic: Yes, these were recently added/refactored. (ROUTING_STRATEGY is indeed deprecated). I'm working on updating the documentation, but with everything moving fast, I'm not finding enough time. You can always ask here what a certain configuration does, if it's not found in the configuration docs.

@Amr Gouhar That's what I though. Keep up the good work, then.
