: The concept of Virtual Organisation (VO) offers various solutions to management, collaboration and coordination issues important for distributed collaborating teams. Deployment of this concept to distributed electronic system design has been addressed in this paper. The article introduces an organizational model of a VO dedicated for System-on-Chip (SoC) design and an architecture of the supporting ICT infrastructure that has been based on the Web Services technology. The developed multi-tier distributed application supports interoperability of heterogeneous computer systems belonging to dispersed design partners. Implementation issues, as well as the experiments verifying the utility of the solution for SoC design planning are shortly reported. 1 Challenges in collaborative design of SoCs Integrated circuits that incorporate whole electronic systems including microprocessors, memories, input/output interfaces, and other peripheral elements on one silicon structure are referred to in...
