A compiler that turns trained ONNX models into bit-exact RTL, FPGA bitstreams, or chip layouts using an open EDA toolchain.

Landing page captured for the 2026-09-18 issue.
For
FPGA developers and open-chip hardware researchers
Worth noticing
The homepage reports one shared engine at roughly 174,000 Sky130 cells, versus roughly 4 million for a per-layer design.

Field notes

The documented flow assigns weights to synthesized case logic and places activations and line buffers in a banked Sky130 SRAM macro. The homepage reports a calibrated INT8 ResNet8 result, a 50 MHz Nexys A7 test path, and approximately 230 MHz post-route Fmax on VU47P. It names the open tools used at each stage, including Yosys, OpenROAD, KLayout, Magic, Sky130, FreePDK45, and ngspice.
