Abstract
An exceptionally effective SoC design is achieved by the user of wrappers that comprise a functionally reconfigurable module (FRM) that is capable of affecting the operational functionality of the wrapper and that, consequently, is capable of affecting the operational functionality of a designed SoC. One embodiment of a core+wrapper combination comprises distinct input and output cells within the wrapper, and a separate FRM. Another embodiment may embed the input and output cells within the FRM. The FRM may be implemented with, for example, a field programmable logic array (FPLA). An additional advance is realized by providing a number of spare leads in the signal paths network that interconnects the various SoC elements.
