Abstract
The present invention provides a method and apparatus for managing a large number of associated interconnects within an integrated circuit involving a modular approach to the macro cell layout. In particular, internal signal paths are created within each macro cell that permit connections to other macros by abutting these macros adjacent to one another. Moreover, these internal signal paths permit efficient distribution of a common source signal to each of such connected macros. The layout of the internal macro cell signal paths of the present invention also permits each of these macros to be reflected about its Y-axis, thereby increasing its versatility in being utilized in various circuit designs.
