Abstract
A user customizable integrated circuit architecture having separate regions for different types of core cells. In an embodiment of the present invention, all asynchronous core cells are placed in a first region and all synchronous core cells are placed in a second region thus allowing clock circuitry to be shared and clock traces to be efficiently routed. Clock buffers may also be placed in the second region. In a second embodiment, high-drive buffers are placed in the second region to enable efficient routing of high-drive power traces to the synchronous cells. Each region also may include metal programmable core cells that may be customized by the user for each design.
