Layering RTL, SAFL, Handel-C and Bluespec constructs on Chisel HCL

Abstract

Chisel is a hardware construction language that supports a simplistic level of transactional programming via its Decoupled I/O primitives. In this paper we describe extensions that layer popular design paradigms on the Chisel substrate. We include RTL, SAFL-style functional hardware description, Handel-C message passing and Bluespec rules. We then briefly discuss interworking between these design styles.
