General-purpose languages simulate simple circuits
Many logic simulation programs are capable of solving virtually any logic-, timing-, and fault-simulation problems (Ref 1). However, these programs are expensive--$1000 to $50,000 or more--and use proprietary and sometimes peculiar modeling languages. Often the more expensive and powerful the simulator, the harder it is to use. In addition, you usually receive these programs in object (binary) code which is practically impossible to understand or modify.
The recently adopted VHDL (VHSIC hardware description language) (IEEE-1076-1987), mandated by the US Dept of Defense, provides a comprehensive basis ...
