SIMSYNCH is a simulator for digital electronics at scales from chip to
board.

 The design files are comprised of Scheme definitions and expressions.
 These design files can be run as a Scheme program at high speed.  The
 design files can also be translated into formats suitable for logic
 compilers (MACHXL, Verilog, and VHDL).

 SIMSYNCH simulates blocks of synchronous logic, signals whose states
 change simultaneously on a clock signal transition.  Each block also
 has a reset signal, which forces all signals to the state specified in
 the design file.  SIMSYNCH can simultaneously simulate multiple blocks
 with different clocks and resets.  Devices can contain multiple blocks;
 Blocks can span multiple devices.

SIMSYNCH is an application of the SCM Scheme implementation.
Documentation is included in the distribution.  Documentation is also
online at:
