  • Publication number: 20230351085
    Abstract: A method includes: loading a circuit design including a plurality of combinational elements and controlled by a user clock; detecting strongly connected components (SCCs) corresponding to the plurality of combinational elements in the circuit design; inserting a plurality of break registers into the circuit design, each break register being between two combinational elements of a corresponding SSC of the SCCs to break the corresponding SCC, the plurality of break registers being clocked by a relaxation clock; detecting, by a processor, during an emulation run of the circuit design, one or more value mismatches across an input pin and an output pin of one or more break registers of the plurality of break registers based on a relaxation cycle of the relaxation clock, the one or more break registers being associated with one or more SCCs exhibiting instability; and reporting an instability event based on the one or more value mismatches.

  • Publication number: 20220396777
    Abstract: In certain example embodiments, the invention provides a method of generating an ex vivo cell-based system comprising dissociating an original tissue sample obtained from a subject into a single cell population; determining an in vivo phenotype of the tissue sample by conducting single-cell RNA analysis on a first portion of the single cells; establishing an ex vivo cell-based system from a second portion of the single cells; and culturing the ex vivo cell-based system in a medium or conditions selected to maintain the in vivo phenotype. In some embodiments, the original tissue sample is a tumor tissue sample, such as a pancreatic ductal adenocarcinoma (PDAC) tumor sample.

  • Patent number: 11176293
    Abstract: The independent claims of this patent signify a concise description of embodiments. A method is provided for reducing a size of an emulation clock tree for a circuit design. The method comprises identifying a fan-in cone of an input of a sequential element of the circuit design; identifying one or more fan-in cone sequential elements which do not directly affect the input of the sequential element; and removing the one or more identified fan-in cone sequential elements of the fan-in cone from the emulation clock tree. This Abstract is not intended to limit the scope of the claims.

  • Patent number: 9460261
    Abstract: A computer-implemented verification system for performing a system level or a system on chip level functional verification of integrated circuit is provided. The computer-implemented system includes one or more processors and a memory storing instructions defined by one or more modules of including a scenario compiler, a verification component and a software library component. The scenario compiler receives a set of verification scenario intents including at least one of test-application intents, constraints, device-programming intents and scenario-control intents. The scenario compiler generates one or more open verification methodology (OVM) and/or universal verification methodology (UVM) compliant test bench sequences and one or more scenario software implementations based on the set of verification scenario intents. The verification component interacts with the integrated circuit using the OVM and/or UVM compliant test bench sequences.
