FPGAs “Flexible” hardware Time to market Hard to program Hard to debug • EDA required ! • C to circuit • Debug • Benchmarking

Our Smalltalk-based EDA legacy

Legacy backfires • Early developments (MADEO) started in 1996 • Fast evolving domain (Moore + Murfy) • Refactoring is not enough to keep in the race • We have to re-design our framework

New direction • We need to shift from • a generic solution to be tailored on demand • To • a repository of model, algorithms, components • In order to deliver • Performances • Scalability • Flexibility • Durability 1 2

LEGACY

Front end C code • High level synthesis (compilation) • Ressources allocation (logic synthesis) Circuit
