    摘要: File paths for a plurality of IC design files in a hardware description language are abstracted by parsing description files, or a directory of description file names, to identify file paths to each of the plurality of design files in a first environment. An index is generated correlating each design file and its respective file path. In use, a file path in a second environment of an application is defined for each design file, and the index is applied to the file paths in the second environment to define full file paths for each design file through the first and second environments. The design files are then applied to the application using the full file paths.

    摘要: A computer-aided circuit design application has a virtual node feature and a design tool. The virtual node feature is adapted to access design specification information in a first data format and to represent the accessed design specification information as a virtual data node object within a list of node objects in a second data format. The design tool is operable on the list of node objects and the virtual data node object.

    摘要: 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.

    摘要: The invention provides a method and system for coupling a SONET/SDH network to a routing network that does not have a single point of failure. Multiple routers are coupled between the SONET/SDH network and the routing network, one for each data path; for example, a first router for the working data path and a second router for the protection data path. The routers intercommunicate to force APS to switch data paths bidirectionally, so as to allow only a single router for each data path.
