Abstract

A system and method for matching the hardware resource requirements of a user module with the available resources of an underlying integrated circuit is shown. Databases are utilized to describe the requirements of a particular user module and the resources of a particular chip. A graphical interface is utilized to relate a selected user module with potentially appropriate resources, and to illustrate alternative placements. This graphical interface utilizes highlights of both the module and the associated resource in patterns, grayscales, or colors to graphically illustrate the relationship between the module and the associated resource.
