PURPOSE: A system and a method for integrated circuit design are provided to increase the efficiency of an integrated circuit design by establishing integrated design environment. CONSTITUTION: The workstations, the compute servers and the design servers are used to design and test integrated circuits. The primary design server contains information pertaining to methodologies and blocks under design. The compute servers contain executable tools used in the creation and test of those designs. The primary design server and the mirror design server are interconnected and share data so as to allow increased throughput and access to design data and processes. In one embodiment the mirror design server is a classic mirror server, that is the mirror design server mirrors the information and data of the primary design server. In the one embodiment the primary design server and the mirror design server are substantially as easily accessible to any workstation, with access to the design servers substantially invisible to users at the workstations. In the described embodiment, however, the mirror design server is a geographically remote server from the primary design server. Mirroring is accomplished by having the primary design server and the mirror design server periodically, e.g. at predefined hours, interrogate the other server to determine if data on the other server has been updated. In one embodiment this is done for all data resident on the other server. In alternative embodiments, data updates only occur if data has changed with respect to specific blocks. Thus, if, as in the described embodiment, information pertaining to a specific block is located in specific directories on a design server, then only changes in those directories are provided to the interrogating server. This allows a convenient mechanism for sharing of data for blocks designed by design teams remote from one another, as well as for periodically updating block information designed at remote locations to a location responsible for overall chip design.
