~ use tclmodules (`.tm`) files instead of pkgIndex.tcl for openlane and openlane_utils
~ change tagging to use the version from the `.tm` files instead of the day of the release
~ include superstable branch in tagging efforts (even though this doesn't mean much in `master`…)
+ Add conditional `set_propagated_clocks` for all clocks in `base.sdc`
~ Condition is true for:
~ CTS STA
~ Global routing STA
~ Global routing optimizations STA
~ Multicorner(signoff) STA
+ Add conditional `set_propagated_clocks` for all clocks after reading an sdc file depending on whether the statement is used in the sdc file for not. Idea is to be backwards compatible with the default behavior of OpenLane of propagating clocks _outside_ the sdc file
+ Add a report for non-propagated clocks
+ Add a report for information regarding clocks
~ Avoid using `/dev/null` for writing DEF files (it tries to create a temp file and fail)
~ PDK now has a default value of sky130A even outside the Makefile
~ PDK_ROOT now set automatically if Volare is installed
~ Upgrade to a newer version of OpenLane 2, which in turns uses `nix-eda`
~ Format nix packages using Alejandra
~ OpenROAD scripts now read liberty files before database files (they are linked together when the database is read)
~ Update Readme to remove Colab and add banner directing people to OpenLane 2
+ Repository is now a Nix flake
~ Change all invocations of `openroad -python` to use `run_odbpy_script` for consistency
~ Change build system from ad-hoc to Nix, still producing a Docker image as a final result
~ Update KLayout scripts to use `klayout-pymod` or properly parse commandline arguments
~ `open_pdks` -> `bdc9412` to match OpenLane 2
- Remove local installer; `nix run .` will run OpenLane natively
~ Reimplemented the default serial/parallel multiplier to be a bit less cryptic and eliminate linter warnings; and added a proper testbench
~ Reimplemented deprecated variable translation behavior to account for the situation where a deprecated variable's value does not match the default for the new value, which causes a crash
~ Slightly improved warning for designs having been black-boxed during STA
~ PDN Generation Updates
~ Renamed `DESIGN_IS_CORE` to `FP_PDN_MULTILAYER` with translation behavior
~ PDN generation will now always attempt to extend to core ring (which is inert if core rings do not exist)
~ Fixed bug where `FP_PDN_MULTILAYER` being set to `0` would attempt to create a core-ring on two layers anyway
~ IR drop now prints a warning if `VSRC_LOC_FILE` is not provided
- Removed deprecation behavior for `GLB_RT` variables - it's been over a year (>=6 mo as promised)
+ Add tt05-i2c-bert (https://github.com/dlmiles/tt05-i2c-bert) to CI
~ Replace instances of ABC command `rewrite` with `drw -l` with `SYNTH_ABC_LEGACY_REWRITE` being set to `1` restoring the older functionality (`0` by default)
~ Replace instances of ABC command `refactor` with `drf -l` with `SYNTH_ABC_LEGACY_REFACTOR` being set to `1` restoring the older functionality (`0` by default)
~ Added `delete t:\$print` to `synth.tcl` to fix designs such as PPU with synthesized prints (as in https://github.com/efabless/openlane2/pull/189)

+ Add a step in CI workflow to replace `/` with `_` in design name for artifact upload.
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`
An exit code of 2 is bypassed. It seems that an exit code that is not 2 is a failure of the python script itself not OpenLane flow. This exception is raised and propagated to the CI. However an exit code of 2 should be propagated as well after a reproducible is made. The CI flow shouldn't attempt to run benchmark when the flow failed.
~ generalize verilator variables:
QUIT_ON_VERILATOR_ERRORS -> QUIT_ON_LINTER_ERRORS
QUIT_ON_VERILATOR_WARNINGS -> QUIT_ON_LINTER_WARNINGS
VERILATOR_RELATIVE_INCLUDES -> LINTER_RELATIVE_INCLUDES

~ `run_designs` now clears run paths before it starts
~ `run_designs` no longer attempts to generated reports for runs that fail at startup

Tested on Apple M1 and AWS Graviton.
+ Add support for multiple-architecture building
+ Support for amd64, ppc64le and arm64v8 added
+ amd64 and arm64v8 will be automatically built by the CI
~ Major CI Overhauls
~ Added composite actions for the Docker build and setting environment variables
~ pdk build is now its own job, and amd64/aarch64 have a job each
~ matrix -> design_matrix, designs only tested on amd64 for performance reasons
~ run/build base docker images now pushed to Docker Hub based on a hash of dependency lists (to work with the buildx `docker-container` driver)
- Remove pandas (overkill for what we're using it for)
- Remove `cugr`, `drcu` *for now* (they're x86-64 Linux-only utilities)
Please excuse the last commit lacking a changelog.
+ PDK installation uses Volare, transparently to the user: all they have to do is type "make", where it will get OpenLane and the PDK
+ CI now uses Volare to either **get** or **build** the PDK (if not found), which speeds up the fastest test set by around 60%.
+ Added rudimentary dependency installation instructions.
+ pyyaml folded into the repo, so users without pip can still run issue surveys
~ Open PDKs updated: Parasitics are now extracted using a rules file based on [spef-extractor](https://github.com/Cloud-V/spef-extractor) as a ***temporary*** measure
~ Issue survey no longer checks for click and pyyaml: a venv is used in those scenarios.
~ OpenLane build no longer uses the host filesystem as an intermediary, instead using a templated dockerfile with an N-stage build for N tools, saving IO operations (40% improvement measured)
~ Old PDK targets renamed to build-pdk-conda, includes SRAM by default
~ Replaced python3 ./env.py issue-survey with `make survey`
- Removed Fault from documentation (until I get the chance to work on it)
+ Added optional multiple **process corner** technology lef support (min/max/nom), in addition to the already existing multiple **timing corner** support (ss/tt/ff). This will also be our nomenclature going fwd.
+ Parasitics extraction now run at all process corners, and multi-corner analysis is run at all three process corners
~ `finishing` -> `signoff`
~ Parasitics extraction and STA are now an independent step instead of being lumped in routing, as part of the signoff block
~ Update OpenROAD
~ Update Open_PDKs, Sky130, and Magic
~ PDK verification made more PDK agnostic outside of env.py
~ Made RCX use LEF files instead of multiple configuration variables/set_rc.tcl
~ `prep_lefs` more or less rewritten
- Removed redundant RCX variables
- Removed `-order_wires` from various `read_def`s in OpenROAD- deprecated, apparently
