sci-electronics chrb@gentoo.org Chris Bainbridge Balsa is an asynchronous circuit synthesis system developed over a number of years at the APT group of the School Of Computer Science, The University of Manchester. Balsa is built around the Handshake Circuits methology and can generate gate level netlists from high-level descriptions in the Balsa language. Both dual-rail (QDI) and single-rail (bundled data) circuits can be generated.
