* Non-fixed layer count for GLB RT adjustments
Remember this kids, nothing is more permanent than a temporary solution.
* GLB_RT_LX_ADJUSTMENT variables consolidated into GLB_RT_LAYER_ADJUSTMENTS, a comma-delimited set of values
* GLB_RT_LX_ADJUSTMENT will continue to be accepted but display a deprecation warning, and will be removed in a later version of OpenLane.
* GLB_RT_L1_ADJUSTMENT value from the PDK is now ignored.
* Bashrc fix (Line wrap problem), or_issue fix
* Only `read_verilog` if there's no CURRENT_DEF: see https://github.com/The-OpenROAD-Project/OpenROAD/issues/1305#issuecomment-968336079 (Practically didn't cause an issue as all DEFs are used without the standalone flag)
* or_issue now supports netlist inputs and no longer generates tarballs: encourages inspecting and running the code before uploading a tarball
* or_issue now also creates tcl, gdb and lldb files
* OpenROAD commit now sedded in instead of GITDIR-NOTFOUND: See last paragraph of https://github.com/Cloud-V/DFFRAM/issues/115
* verilog2def -> init_floorplan
Some files still retained the name of a floorplanning tool we're no longer using. It has been removed.
* netlist locations
Netlists generated as part of later steps were placed under `synthesis/`. They have been moved to their proper locations.
* Build tweaks
`make openlane` now actually builds the container. `make pull-openlane` has been added with the original functionality.
The git commit has been placed in the container at `/git_version`.
A custom `.bashrc` has been added.
Non-standard `echo -ne` invocations replaced with `printf`.
* Issues
verify_versions now works without a `PDK_ROOT` set (`$openlane_root/pdks`)
clarified issue template
* Rewrite or_replace.tcl
That script used a lot of internal swig commands with an unstable API/unpredictable behavior. Resolves#697.
* Expose `max_displacement` flag for detailed placement
This was added at some point as a replacement to the diamond search height thing and is necessary for macros.
* Add OpenROAD GUI/Tcl Readline
Resolves#642. Note that this addition will be intentionally undocumented and is intended more for people who absolutely want it.
MISC:
* CI fast fail off/always push image
The CI will report failures still, but will still publish an image and create a tag. Additionally, other tests won't be killed on the first failure.
* Naming convention changes
* `docker_build/` -> `docker`: Just is more consistent with literally every other codebase that uses Docker ever.
* Removed `or_` prefix from OpenROAD scripts: redundant: They're all already under a folder called "openroad." The distinction no longer makes any sense as there are no separate scripts for the previously standalone utilities.
