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. The designs are qualified, tested, and verified by other tools. The tools further optimize the placement and timing of the blocks on the chip with respect to each other and with respect to placement on a board. The suite may be run as batch processes or can be driven interactively through a common graphical user interface. The tools also have an iterative mode and a global mode. In the iterative mode, one or more of the selected tools can generate the blocks or modify a design incrementally and then look at the consequences of the addition, or change. In the global mode, the semiconductor product is designed all at once in a batch process as above and then optimized altogether. This suite of generation tools generates design views including a qualified netlist for a foundry to manufacture.

A standardized silicon platform chip has a substrate surface with an array of unconnected transistors that surround islands. The islands have circuit elements that are interconnectable within each island to form a plurality of varied circuit functions for each of the islands. The varied circuit functions include both application functions and clock functions. Interconnect layers are deposited over the substrate surface to interconnect the circuit elements within each island to complete the varied circuit functions. The varied circuit functions include varied levels of integration including at least gates, flip-flops, clock trees, and oscillators. The varied circuit functions are custom connectable to the array of unconnected transistors to form standard clock resources for the standardized silicon platform chip.
摘要:
A electronic design automation tool, apparatus, method, and program product by which design requirements for an intended semiconductor product and the resource definitions of a semiconductor platform are input. From the design requirements and the resource definitions, parameters specific to clocking are derived, e.g., clock property information, clock domain crossing information, and clock relationship specification. The tool and method embodied therein validates the clocking parameters of the design requirements with the resource definitions and invokes errors if the parameters are not realizable. Once the desired clocking parameters are consistent with the actual clocking parameters, correct physical optimization constraints and timing constraints are generated for the clocks. An iterative process can achieve correct and minimal clocking constraints.

A method for creating constraints for integrated circuit design closure is provided. Design specifications are captured before a design flow is started. The design specifications are checked for compatibility with the design flow. The design specifications are stored in a database. Output transforms are applied to the design specifications to create orthogonal constraint sets which are tuned for both a specific tool and a positional use of the specific tool within the design flow.
