Ruby

1. A {relational language} designed by Jones and M. Sheeran in

1986 for describing and designing circuits (a {hardware

description language}). Ruby programs denote {binary

relation}s and programs are built-up inductively from

primitive relations using a pre-defined set of {relational

operator}s. Ruby programs also have a geometric

interpretation as networks of primitive relations connected by

wires, which is important when layout is considered in circuit

design.

Ruby has been continually developed since 1986, and has been

used to design many different kinds of circuits, including

{systolic array}s, {butterfly network}s and arithmetic

circuits.
