Abstract

The difficulty of emb edded system co-design is increasing rapidly due to the incr easing complexity of individual parts, the variety of parts available and pr essure to use multiple processors to me et performanc e criteria. V alidation tools should contain sever al features in order to keep up with this trend, including the ability to dynamically change detail levels, built in protection for intellectual property, and supp ort for gradual migr ation of functionalityfrom a simulation environment to the real hardware. In this paper, we present our appr oach to the problem which includes a geographically distributed co-simulation framework. This fr amework is a system of nodes such that each can include either portions of the simulator or real hardware. In supp ort of this, the framework includes a me chanism for maintaining consistent versions of virtual time.
