DCim++ is a C++ library developed for object oriented hardware design, modeling and distributed simulation. DCim++ enables C++ to be used as an OO HDL, which supports concurrency in description, inheritance in design and distributedness in simulation. Design simulation results are obtained by running C++ programs on a network of workstations. The message passing interface (MPI) library has been used in the implementation of DCim++ as the basis of communications required for distributed simulation. In our simulation scheme, we have not considered any central management unit in order to defy performance degradation, instead only a coarse-grain synchronizer is used to keep the distributed components synchronized. This paper explores the structure of the DCim++ library and its mechanisms. The process a designer has to go through in order to design a system using DCim++ and conduct its distributed simulation leaving communication complications to DCim++, has also been presented. Finally, the results of our uniprocessor and distributed simulations for ISCAS benchmark circuits show high degrees of performance gains
