Virtual simulation of distributed IP-based designs

One key issue in design flows based on reuse of third-party intellectual property (IP) components is the need to estimate the impact of component instantiation within complex designs. In this paper we introduce JavaCAD, an Internet-based EDA tool built on a secure client-server architecture that enables designers to perform simulation and cost estimation of circuits containing IP components without actually purchasing them. At the same time, the tool ensures intellectual property protection for the vendors of IP components, and for the IP-users as well. Moreover, JavaCAD supports negotiation of the amount of information and the accuracy of cost estimates, thereby providing seamless transition between IP evaluation and purchase
