    摘要: A system and method for verifying system-on-chip interconnect includes a first linear feedback shift register coupled to an output interface of a first system-on-chip component, a second linear feedback shift register instantiated in a second system-on-chip component, and a comparator coupled to the second linear feedback shift register and the input interface of the second system-on-chip. Another method for verifying includes generating a pseudo-random number sequence with the first linear feedback shift register and the second linear feedback shift register using an identical first initial state, and comparing an output of the first linear feedback shift register with an output of the second linear feedback shift register and reporting a miss-compare.

    摘要: Disclosed are embodiments of a manufacturing method that establishes a library of pre-made and pre-qualified masks for patterning different blocks of circuitry that meet established performance and timing requirements. The embodiments of the method use stepped exposures of multiple masks, including at least one mask selected from this library, to pattern a chip design onto a silicon wafer, where the chip design is made up of two or more interconnected blocks of circuitry. Consequently, for a given integrated circuit design, pre-made/pre-qualified mask(s) can be selected from the library to pattern one, some or all blocks of circuitry for the design. Optionally, additional masks can be specially made and qualified to pattern other block(s) of circuitry (e.g., application specific logic) within the design. The blocks of circuitry patterned in this manner can be electrically connected via generic or customized interfaces in order to complete the chip design.

    摘要: An apparatus for monitoring the temperature of an integrated circuit device includes a conductive wiring pattern formed on the integrated circuit device, extending into areas of the device to be monitored. A deterministic signal source is configured to generate a deterministic signal along the conductive wiring pattern, with one or more return paths tapped from selected locations along the pattern. A temperature change determination circuit is coupled to the one or more return paths and to a reference signal taken from the deterministic signal source. The circuit is configured to determine a delay between the reference signal and a delay signal traveling through at least a portion of the wiring pattern and a corresponding one of the return paths.
