    摘要: Disclosed are embodiments of on-chip identification circuitry. In one embodiment, pairs of conductors (e.g., metal pads, vias, lines) are formed within one or more metallization layers. The distance between the conductors in each pair is predetermined so that, given known across chip line variations, there is a random chance (i.e., an approximately 50/50 chance) of a short. In another embodiment different masks form first conductors (e.g., metal lines separated by varying distances and having different widths) and second conductors (e.g., metal vias separated by varying distances and having equal widths). The first and second conductors alternate across the chip. Due to the different separation distances and widths of the first conductors, the different separation distances of the second conductors and, random mask alignment variations, each first conductor can short to up to two second conductors. In each embodiment the resulting pattern of shorts and opens, can be used as an on-chip identifier or private key.

    摘要: Method for correcting timing failures in an integrated circuit and device for monitoring an integrated circuit. The method includes placing a first and second latch near a critical path. The first latch has an input comprising a data value on the critical path. The method further includes generating a delayed data value from the data value, latching the delayed data value in the second latch, comparing the data value with the delayed data value to determine whether the critical path comprises a timing failure condition, and executing a predetermined corrective measure for the critical path. The invention is also directed to a design structure on which a circuit resides.

    摘要: The embodiments of the invention provide an apparatus, method, etc. for a task based debugger (transaction-event-job-trigger). More specifically, an integrated event monitor for a SOC comprises functional cores each having a functional debug logic element. The cores are connected to an interconnect structure that links the functional debug logic elements. Each functional debug logic element is specifically dedicated to a function of its corresponding core, wherein the functional debug logic elements generate a table of function-specific system events. The system events are function-specific with respect to an associated core, wherein the system events include transaction events, controller events, processor events, interconnect structure arbiter events, interconnect interface core events, high speed serial link core events, and/or codec events.
