~ Add reports for timing multi-corner STA across all process corners
~ Sort min/max report outputs by slack
~ Combine Slew, Fanout, Capacitance and Annotation Checks into one `_sta.checks.rpt`
~ Combine TNS, WNS, Worst_Slack into one `_sta.summary.rpt`
~ Fix regression in #1675 where logs were renamed and reports were not getting generated for some steps
~ Update documentation
\- 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
Fix https://github.com/The-OpenROAD-Project/OpenLane/issues/1701
\~ 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
compare_regression_reports.py:
~ Change metric name antenna_violations -> pin_antenna_violation
~ Handle "bad" encoding of csv report files
config.py:
~ Sort result from get_config_for_run and configuration_values for consistency

net_antenna_violations as reported by openroad antenna checker

~ Calculate cells_per_mm based on Non-phyCells instead of synth_cell_count
~ Rename

+ 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
\+ Add `QUIT_ON_SYNTH_CHECKS` (perhaps needs a better name?)
\~ `run_tcl_script` now logs warnings to `.warnings` file
\~ `run_tcl_script` now logs errors to `.errors` file

\~ Enable `QUIT_ON_XOR_ERROR` by default
+ Update reproducible uploading docs
+ Documented a number of missing configuration variables
~ Fix an issue where netlist STA reproducibles would attempt to use `CURRENT_ODB` and crash
- Removed a number of unused configuration variables
For `padringer.py`:
\+ Add output `ODB` and optional `DEF`
\+ Add `--odb-lef` which is the lef file to included with `ODB` output file.
\+ `--width` and `--height` are no longer required as they can be fetched from the config file
\+ `--input-lef` and `--padframe-config` click options are now multiple
others:
\+ Add `FP_PADFRAME_CFG` which points to configuration file passed to `padringer.py`
\+ Add `GPIO_PADS_PREFIX` to parameterize prefix passed to `padringer.py`
\+ Add `padframe_gen_batch` to capture all of the above in a simple wrapper
\+ Add klayoutrc to OL images
\+ Made klayout scripts launchable as commands

+ Add JSON support to "matrix" mode
~ Rename "regression mode" to "matrix", as it more accurately reflects a combination of variables
~ Replace bizzare "regression script" with a JSON file achieving basically the same thing
~ `run_designs` now clears run paths before it starts
~ `run_designs` no longer attempts to generated reports for runs that fail at startup
~ `verify_versions` no longer attempts to check the PDK if the environment variable PDK is not set
~ `scripts/config/config.py:get_config` -> `get_config_for_run` (more accurate)
~ `scripts/config/tcl.py:read_tcl_env` no longer exits unilaterally, raises an exception normally
- Remove Test #892
- Remove `Tcl` support from matrix mode: not tenable
- Remove Tcl extraction shell script

Resolves#1458
\~ document the right report file for `run_or_antenna_check`
\~ fetch the correct report/log file for openroad antenna reports
\~ capture pin violations and net violations
\~ fetch the correct report file for magic antenna report
~ fix cell name in `user_proj_example2.gds` in `caravel_upw` testcase. the cell name was incorrectly set to `user_proj_example`
~ update magic version.
+ add configuration variable `MAGIC_GDS_ALLOW_ABSTRACT` to allow abstract view of macros during magic gds generation which was previously allowed in magic. The new default is set to disallowed as usually having abstract view is caused by an error in configuration.
~ check the right flags while setting pin thickness and multiplier
~ change default values of FP_IO_*EXTEND to 0
Co-authored-by: Donn <me@donn.website>

\+ Add `QUIT_ON_LONG_WIRE` which fails the flow if any wires are flagged for length
~ Update all `$::env(OPENROAD_BIN) -exit -python` invocations to include `-no_init` to suppress message about rc file
~ Replace ill-fitting `$::env(OPENROAD_BIN) -exit -python` invocations with just `python3`
~ Replace local install check with a simple git directory check
+ Formalized concept of "exposed variables", environment variables that are exposed to `config.json` during processing
+ `dir::` is no longer a special case: all `ref::` prefices referencing a path now have the ability to glob inside said path
+ Made `dir::`, `pdk_dir::` and `scl_dir::` short-hands for various `ref::`s
+ Add `proc erase_box` to OpenLane
