[!NOTE]
This project has been merged into the Loom Synthesis Engine. Updates to Floret will likely be infrequent as a result. See Loom for a more up-to-date version.

Floret is an automated custom cell generator. The underlying algorithms are built from the following papers:

  1. Stauffer, André, and Ravi Nair. "Optimal CMOS cell transistor placement: a relaxation approach." 1988 IEEE International Conference on Computer-Aided Design. IEEE Computer Society, 1988.
  2. Chen, Howard H., and Ernest S. Kuh. "Glitter: A gridless variable-width channel router." IEEE transactions on computer-aided design of integrated circuits and systems 5.4 (1986): 459-465.
  3. Deutsch, David N. "A “Dogleg” channel router." Papers on Twenty-five years of electronic design automation. 1988. 111-119.

Build and Install

Install all dependencies sudo apt install libqhull-dev zlib1g-dev python3.10-dev git submodule update --init --recursive

Build the executable make

Examples

See Releases for example generated layouts.

This will generate a GDS library with a nand gate in nand.gds using the sky130 tech file provided in the tech directory. ./floret-linux -p -c cells -t tech/sky130.py test/nand.spi

Status

Floret is being tested on Skywater's 130nm process technology node, layouts are largely DRC/LVS clean.
