Die are identified for each standard hard function, such as memory, processing, I/O and other standard functions and one or more user-configurable base platforms are selected that, when configured, execute the custom soft functions. Optionally, the substrate is laminated to the die and the platforms are attached to the substrate. Testing is performed by defining the configured base platforms coupled to logic representing the die and their connections and performing placement and timing closure on the combination.

Abstract: A set of tools is provided herein that produces useful, proven, and correct integrated semiconductor chips. Having as input either a customer's requirements for a chip, or a design specification for a partially manufactured semiconductor chip, the tools generate the RTL for control plane interconnect; memory composition, test, and manufacture; embedded logic analysis, trace interconnection, and utilization of spare resources on the chip; I/O qualification, JTAG, boundary scan, and SSO analysis; testable clock generation, control, and distribution; interconnection of all of the shared logic in a testable manner from a transistor fabric and/or configurable blocks in the slice. The input customer requirements are first conditioned by RTL analysis tools to quickly implement its logic. The slice definition and the RTL shell provides the correct logic for a set of logic interfaces for the design specification to connect. The tools share a common database so that logical interactions do not require multiple entries.
