## Quick start
TODO: make this into a more formal makefile flow
```
# Pre-processing
# Create speed.json
./speed.sh
pushd speed
make
popd
# Create csvs
pushd timgrid
make
popd
pushd projects/placelut
make N=1
csv=specimen_001/timing3.csv
# Main workflow
# Discover which variables can be separated
python3 timfuz_rref.py --simplify --out sub.json $csv
# Verify sub.json makes a solvable solution
python3 checksub.py --sub-json sub.json group.csv
# Separate variables
python3 csv_flat2group.py --sub-json sub.json --strict $csv group.csv
# Create a rough timing model that approximately fits the given paths
python3 solve_leastsq.py --sub-json sub.json group.csv --out leastsq.csv
# Tweak rough timing model, making sure all constraints are satisfied
python3 solve_linprog.py --sub-json sub.json --sub-csv leastsq.csv --massage group.csv --out linprog.csv
# Take separated variables and back-annotate them to the original timing variables
python3 csv_group2flat.py --sub-json sub.json --sort linprog.csv flat.csv
# Final processing
# Create tile.json (where timing models are in tile fabric)
python3 tile_txt2json.py timgrid/specimen_001/tiles.txt tiles.json
# Insert timing delays into actual tile layouts
python3 tile_annotate.py flat.csv tilea.json
