+ Added a new target to the Makefile, `make m`, which mounts the directory at the same path in the container as it is in the host
~ Changed Makefile to mount an empty folder where `install` is so there's less confusion
~ Updated banner per @shalan's recommendation
- Remove `make veryclean` which users may not use consciously and end up nuking their designs
~ Set default `FP_IO_MODE` to 0.
~ Better `FP_IO_MODE` documentation.
~ Change the behavior of `FP_IO_MODE` 0:
1. Run global placement with `-skip_io` flag.
2. Run io placement (again).
3. Run global placement.
If `FP_IO_MODE` is 1, steps 1 and 2 are skipped.
~ Change tcl functions `global_placement_or` and `place_io` to allow for the changes mentioned above.
- Remove `cvc_rv` utility (upstream no longer willing to support it as part of the flow)
~ Fix bug with OpenLane docker image builder copying run folders
+ Add PNR_SDC_FILE
+ Warn when (PNR|SIGNOFF)_SDC_FILE are not overwritten by the user.

+ Added `make docs` target to primary Makefile to generate documentation
~ Update documentation dependencies
~ Updated `tcl.py` to handle JSON lists of elements including whitespace by joining them with a comma (unless one of the elements already contains a comma), resolving odd JSON syntax
~ Re-organized and re-order configuration variables and edited descriptions for general consistency as well as adding anchors
~ Update all documentation dependencies
~ Fixed a number of broken links
- Remove dependency on `docutils` and `sphinx-autobuild` (both unused)
- Remove two of the custom documentation extensions
~ Move test designs to a separate repository and add it as a submodule.
~ Adjust test set to refer to designs in submodule.
~ Change design_dir in `run_tests.py` for artifact upload in the CI.
~ Fix fail condition on design name mismatch in `compare_regression_reports.py`
~ Print a better error message for design name mismatch mentioned previously.
~ Change regression benchmark to point reflect submodule change.
~ Change documentation to reflect new paths of designs.
+ Add aes_user_project_wrapper to ci designs to test EXTRA_SPEFS.
+ Add a step in CI workflow to replace `/` with `_` in design name for artifact upload.
~ Classified PDK variables by user modifiability

~ `SYNTH_MAX_TRAN` -> Moved into PDK as `MAX_TRANSITION_CONSTRAINT`
~ `SYNTH_CAP_LOAD` -> `OUTPUT_CAP_LOAD`
- Removed `DEFAULT_MAX_TRAN` from PDK (unused)
Script uses regular expressions to create a set of documents variables and a set of used variables and compare them against each other. Some variables are internal, unexposed and others. These variables are whitelisted. See https://github.com/The-OpenROAD-Project/OpenLane/issues/1889
\+ Add documentation for `QUIT_ON_XOR_ERROR`
~ Rename `antenna.log` to `arc.log` and `magic_antenna.log` to avoid confusion
~ Separate PDK porting instructions and PDK variables
~ Add deprecated variables to documentation
~ Make existing deprecated variable documentation formatting-consistent and with replacement instructions
- Remove defaults from deprecated variables (they don't have any)
- Remove `LIB_MIN`/`LIB_MAX`: enough time has passed and PDK variables are annoying to deprecate

~ generalize verilator variables:
QUIT_ON_VERILATOR_ERRORS -> QUIT_ON_LINTER_ERRORS
QUIT_ON_VERILATOR_WARNINGS -> QUIT_ON_LINTER_WARNINGS

\- Remove UMich ECO timing report vestiges
---
Based on feedback from @shalan, Fixes#875
~ set min distance in cfg file instead of using `FP_IO_MIN_DISTANCE`
~ don't quit when min distance < legal min distance and use legal min distance. by definition if min distance is illegal it is "minimum" and we can use a higher value
~ `min_distance` is not min spacing - adjust legal tracks in `io_place.py` under that assumption
+ add wrapper.tcl to capture magic errors ported from openlane2
~ use lef/def or gds instead of mag to write a lef through MAGIC_LEF_WRITE_USE_GDS
~ print lef write log file path

\~ Move Yosys check quitting entirely to Python script
\~ Update DRC rosetta to use streams instead of in-memory translation (for most of them)
\+ Add `SYNTH_CHECKS_ALLOW_TRISTATE` that allows tristate buffers in yosys `check`
\~ Fix wrong default value of `RUN_HEURISTIC_DIODE_INSERTION` in documentation
\~ Move Yosys check quitting entirely to Python script, can ignore tristate buffer-related warnings
\~ Update DRC rosetta to use streams instead of in-memory translation (for most of them)
\+ Add `EXTRA_SPEFS`
\+ Use `VERILOG_FILES_BLACKBOX` in sta. Allow skipping a file by adding a comment `/// sta-blackbox`
\+ Detect blackboxed modules in typical-corner STA during sign off and warn the user about it
\+ Add `run_sta_script` used in multicorner sta
\+ Support sta in `or_issue.py`
\+ Support sta in `run_tcl_script`
\+ Check if regex defined in `FP_PDN_MACRO_HOOKS` has a match. Fixes https://github.com/The-OpenROAD-Project/OpenLane/issues/1599
\~ Wrap `set_global_connections` around a flag since it is not supported by opensta
\~ Run multicorner sta using standalone sta application for hierarchical
sta support
\~ Move `sta_multi_corner.tcl` to `scripts/openroad/sta/multi_corner.tcl`
\~ Don't delete target directory of `-save` for multicorner spef files
\~ Merge multi_corner sta and single corner into one script.
\~ Split `RUN_STANDALONE` embedded inside openroad steps, which calls sta after, to another sta step run after said openroad step
\- Remove `report_design_area` in `multi_corner.tcl` since it is not supported by standalone OpenSTA
\- Remove `scripts/openroad/sta.tcl`
~ In `yosys`, call `check -assert` at the correct stage. This requires expanding `yosys` built-in command `synth` to its original sub-commands found in https://github.com/YosysHQ/yosys/blob/master/techlibs/common/synth.cc and inject `check -assert` in the middle of the expanded command. Experimentally, this was the only way to properly capture used wires that do not have a driver.
Additional synthesis checkers guarded with `QUIT_ON_SYNTH_CHECKS`:
\+ Add `check_latches`
\+ Add `check_out_of_bound`
\+ Add `check_resizing_cell_port`

+ Add DIODE_ON_PORTS
+ Add HEURISITIC_ANTENNA_INSERTION_MODE
~ Update benchmark results for SW_HD
~ Apply DIODE_PADDING in dpl_cell_pad which also runs after RUN_HEURISTIC_DIODE_INSERTION
run_designs.py:
~ Change default config to `config` instead of `config.json` to allow for designs with
tcl default config
~ Change logging format
+ Print SUCCESS when a design is finished
~ Use extra parameters `params.keys()` instead of `ConfigHandler.get_header()` to build
report csv header. This fixes inconsistencies between csv header and values reported
compare_regression_design.py:
~ Change metric name antenna_violations -> pin_antenna_violations
~ Handle "bad" encoding of csv report files
~ Quit when a report is perceived as invalid
~ Don't print output file name to stderr

+ Add warning when DPL_CELL_PADDING is set to greater than GPL_CELL_PADDING
~ Update PDK, changing the default values of GPL/DPL cell padding to `0`
~ **Use $HOME/.volare as the default PDK location**
~ `PL_TARGET_DENSITY` incorporates value of `GPL_CELL_PADDING` in calculation
~ Updated various config files to handle new default padding options
~ CI bugfixes + support for Volare 0.7.1
~ Move `QUIT_ON` variables outside of checker functions
~ Move final timing checks to a flow step: `run_timing_check_step`
~ Replace a couple of loose `file exists` with `assert_files_exist` calls
~ Replace all `flow_fail` across the flow with `throw_error`, which behaves accordingly:
* If running an interactive script, `flow_fail` is called
* Else, the errors are propagated upwards, where `flow.tcl` is to catch it
~ Rename `try_catch` to `try_exec` as it now propagates the error, with translation behavior
- Remove UMich experimental ECO flow
