MODSIM II - An Object Oriented Simulation Language For Sequential And Parallel Processors

Abstract

MODSIM II is an object-oriented general purpose and simulation language designed to work with both sequential and parallel processors. Its objects have both single and multiple inheritance. It has a single syntax that works across a variety of systems including main frames, work stations and PC's. A parallel version is currently under development on the BBN Butterfly parallel computer under the Time Warp operating system. MODSIM II is based on the syntax of Modula-2. The majority of statements are identical with those in Modula-2. It has a few additional constructs that let the user write discrete process simulations. MODSIM II has built-in object oriented constructs, including single and multiple inheritance, data abstraction and information hiding. In addition, it supports separate compilation. This makes it useful for large projects. It contains interactive dynamic graphics to improve input and output.
