    摘要: A system includes an automated place and route tool to generate a layout of an integrated circuit (IC) die based on a gate level circuit description. A machine readable persistent storage medium includes a first portion encoded with a first gate-level description of first and second circuit patterns to be formed on first and second IC dies, respectively, and a second portion encoded with a second gate level description of the plurality of circuit patterns received from the tool. The second gate level description includes power and ground ports, and the first gate level description does not include power and ground ports. A processor-implemented verification module is provided for comparing the first and second gate level descriptions and outputting an error report if the second gate level description has an error. The verification module outputs a verified second gate-level description of the first and second circuit patterns.

    摘要: A system and method is disclosed for functional verification of multi-die 3D ICs. The system and method include a reusable verification environment for testing each die in a stack of dies individually without having to simultaneously operate all of the dies in the stack. The system and method includes converting an input/output (“IO”) trace from a die verification test from a first format to a second format to improve performance.

    摘要: Systems and methods are disclosed for testing a stack of dies and inserting a repair circuit which, when enabled, compensates for a delay defect in the die stack, particularly where the defect is located in the inter-die data transfer path. Intra-die and inter-die slack values are determined to establish which die or dies in the die stack would benefit from the insertion of a repair circuit.

    摘要: A method of transmitting data is disclosed. At least one system block of a system-on-chip (SoC) is modeled at an untimed functional level in first and second untimed functional models. First and second transaction level (TL) models of the at least one system block system block are modeled at a transaction level (TL) using the first and second untimed functional models, respectively. First and second cycle accurate (CA) models are modeled at a cycle accurate (CA) level using the first and second TL models, respectively. Data is transmitted from the first untimed functional model to the first CA model, from the first CA model to the second CA model via a CA bus, and from the second CA model to the second untimed functional model.
