The COSY Simulation Language
Abstract
COSY is a new simulation language for the simulation of COmbined continuous
and discrete SYstems. With its continuous subsystem, COSY represents a new
CSSL type simulation language. COSY coded continuous simulation programs look
quite similar to CSMP coded programs. As a matter of fact,the COSY definition
even constitutes a superset of CSSL, since many additional structuring elements
are incorporated (e.g., for comfortable modeling of variable structure systems.
For the discrete subsystem, a combined process and event orientation has been
used. Discrete COSY programs will, thus, look similar to SIMULA-67 or GPSS-V
programs. In addition to these two subsystems, new elements have been incorporated
into the language definition to allow for coding combined continuous and discrete
systems as we11. A PASCAL coded preprocessor translates COSY input into GASP-V
executable code, where GASP-V is an ANSI FORTRAN-IV coded subroutine package
presented at the last IMACS Congress in Delft.
