Synchronous digital circuits as functional programs

Peter Gammie
2013 ACM Computing Surveys  
Functional programming techniques have been used to describe synchronous digital circuits since the early 1980s and have proven successful at describing certain types of designs.  ...  The resulting net lists (circuit schematics represented as graphs) are semi-automatically mapped to an implementation technology and laid out for realisation in silicon.  ...  Here we focus on the successful tradition of rendering synchronous digital circuits and similar systems as more-or-less pure first-order functional programs.  ...

MONTAGE: An FPGA for synchronous and asynchronous circuits [chapter]

Scott Hauck, Gaetano Borriello, Steven Burns, Carl Ebeling
1993 Lecture Notes in Computer Science  
Asynchronous circuits have different requirements than synchronous circuits, which make standard FPGAs unusable for asynchronous applications.  ...  Similar problems also exist for interfacing separately-clocked synchronous circuits. We discuss these problems, and demonstrate how the Montage FPGA satisfies the demands of these classes of circuits.  ...  Thus, they must appear as special, built-in blocks in any FPGA which hopes to implement asynchronous circuits, but which does not allow mappings to program circuits at the transistor level (for an example  ...
