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
+ Pin all pip versions
~ Verify versions made more PDK independent, reads .config/nodeinfo.json
~ Make `requirements_lint.txt` separate
~ Update to new Black: changes to ** operator formatting
~ Various spelling/grammar fixes
~ git:// -> https://
* In run_non_interactive_mode make -no_lvs -no_drc -no_antennacheck into flags
These don't need an argument and the code was already looking in flags_map.

* in ioplacer.tcl use proper commands rather than internals
Signed-off-by: Matt Liberty <mliberty@eng.ucsd.edu>
* Add DFF_LIB_SYNTH optional variable for dfflibmap
dfflibmap can only take a single liberty file. If LIB_SYNTH has multiple
files then DFF_LIB_SYNTH is the one with all the sequential elements.
If unset then LIB_SYNTH will be used for backward compatability.
Needed for asap7 which uses multiple liberty files.

* Fix Odd Antenna Issue By Reverting OpenROAD
The best thing to happen to OpenLane since OpenLane.
Variables related to output files: i.e. logs, results and reports, are becoming more uniform.
* Variables now point to folders
* Variables now called `{stage}_{type}s`
* All variables renamed to be tool-generic
* magic, klayout, cvc and lvs all unified, renamed "finishing"
* Better flow runtime calculation
* All step runtimes are now stored in a yaml file, which can easily be read by a human or parsed by a computer.
* Better step indexing
* You have to increment the step index explicitly using `increment_index`.
* Functions that take log arguments now require you to not use an indexed file, it's their responsibility to index them.
* Changed names for many logs to make more sense
* A plethora of files being moved and/or renamed
* Yosys scripts were moved into their own folder
* All references to OpenLANE that are not a published paper have been replaced with OpenLane
* Copyright dates updated on some files
* 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.
This makes a number of internal improvements to the docker build process.
* A common build base
This common build base utilizes the dependency list outlined in `/dependencies` for both yum and pip, with the exception of cu-gr and dr-cu which use an... interesting (read: obtuse) build system. Speaking of...
* A pre-compile dependency list
This allows for the installing of dependencies that may need to be needed to compile *other* dependencies, incl. wheel, pyinstaller, devtoolset, etc.
* Builds now use tarballs
Git is no longer used, saving us the time needed to check out the *entire commit history every single time we build.* To handle submodules, I wrote a special script. Only OpenROAD uses submodules anyhow.
* Rewrote final image
The final image's Dockerfile was a mess. The new one also uses the dependency list and is better organized.
* OpenLane is now mounted to `/openlane` instead of `/openLANE_flow`
We don't really use `openLANE`, branding was settled on `OpenLane`, except I think it's better for everyone's sanity if I avoid capital letters altogether.
~ RUN_SIMPLE_CTS no longer runs the Simple CTS if CLOCK_TREE_SYNTH is off.
~ TritonCTS will no longer run if RUN_SIMPLE_CTS is on.
- wbqspiflash was apparently duplicated between the FTS and ETS so it's been removed from the ETS.
+ ./install.py greatly expanded to ./env.py, a python script consolidating all manners of environment configuration including installation and docker option generation
+ issues are now required to use ./env.py to survey the environment
+ installs to arch/manjaro now supported
~ python no longer asks to install, it creates a virtual environment
~ centos7 -> centos-7 (for consistency)
~ scripts reorganized: i need that top level as pristine as humanly possible
- removed csv2html. just use a viewer
