  • Patent number: 7058864
    Abstract: Systems, methods, software products test a memory cache of a processor that includes a test engine (e.g., a BISTE). High level test source code is formulated to use routines in API source code that, when compiled into machine test code, interfaces with the test engine. The machine test code is executed with the processor to test the memory cache to detect one or more faulty memory blocks in the memory cache. If any of the faulty memory blocks are detected, the test engine is instructed, through the machine test code, to set one or more bits in registers to functionally replace the faulty memory blocks with redundant blocks of the memory cache.

  • Publication number: 20040143531
    Abstract: Techniques are disclosed for automatically synthesizing information from a plurality of computer-readable integrated circuit package models. In one embodiment, each of the plurality of package models contains information descriptive of a distinct package. Such information may include, for example, intra-package path lengths and/or propagation delays of signal nets in the modeled packages. Techniques are disclosed for automatically synthesizing such information to produce, for example, aggregate path lengths and/or propagation delays of the signal nets across all of the modeled packages. Such synthesis may be performed even when the package models use mutually inconsistent signal net naming conventions and the modeled packages are composed of different materials. Techniques are also disclosed for providing information to the package designer to assist the package designer in improving the design of the package models.
