FPGA synthesis takes so long that iteration is slowUnreviewed
20132026- Compiling a design onto the FPGA takes 1 to 20 hours, making it impractical2025-12-23
- FPGA synthesis takes a long time, making iteration slow2021-05-16
- Synthesis and place-and-route take excessive time, making reprogramming and debugging slow2016-10-14
Unreviewed issues were grouped by machine: Claude Haiku labelled each comment as a usability complaint, named what it's about and summed up the problem in a line, and a small model grouped similar problems. Nobody has checked them by hand. Expect mistakes.
