%T Advanced Silicon Prototyping in a Reconfigurable Environment %A Matt Aubury, Ian Page, Dominic Plunkett, Matthias Sauer, Jonathan Saul %E Peter H. Welch, Andr\[`e] W. P. Bakkers %B Proceedings of WoTUG\-21: Architectures, Languages and Patterns for Parallel and Distributed Applications %X A flow is proposed which offers a programming approach to the systems design of application specific micro\-controllers. This flow is based on Handel\-C, an occam\-based language with C\-like syntax for hardware compilation. Tools have been developed for compilation and concurrent simulation (co\-simulation) of hardware and software parts of a system, and a reconfigurable board has been designed which can be used for rapid prototyping of the application specific micro\-controller. The final design can be compiled into a structural VHDL netlist for a standard cell ASIC process.
