This paper describes behavioral compilation tools built for use in an intelligent silicon compiler. These tools allow the user or an expert system to compile behavioral descriptions to a register transfer level under user-imposed constraints. A flexible design model offers a combination of design features previously unavailable in behavioral compilers such as multicycle, chained, and pipelined function units along with the ability to choose between bus- and mux-based connectivity models. Furthermore, we present a new design strategy that allows easy exploratory design and we describe algorithms for state synthesis and connectivity binding that achieved higher quality designs than previous systems on selected benchmarks. The code for this project is run under 42 BSD Unix on a VAX 11 780 and is written in C.
