  • Patent number: 11907627
    Abstract: In an integrated circuit (IC) assessment method, an artificial intelligence (AI) component comprising at least one artificial neural network (ANN) is trained to transform layout rendering tiles of a rendering of a reference IC into corresponding reference layout image tiles extracted from at least one layout image of the reference IC. Using the trained AI component, standard cell layout renderings of a library of GDSII or OASIS standard cell layout renderings are transformed into as-fabricated standard cell layout renderings forming a library of as fabricated standard cell layout renderings. Instantiated standard cells and their placements in the layout image of an IC-under-test are identified by matching the instantiated standard cells with corresponding as-fabricated standard cell layout renderings retrieved from the library of as fabricated standard cell layout renderings.

  • Patent number: 11874323
    Abstract: Disclosed is a JTAG-based burning device, including controllable switches arranged between a TDI terminal of a JTAG host and a first chip, and between two adjacent chips, and further including a master controllable switch module arranged between each chip and a TDO terminal of the JTAG host, wherein the JTAG host may, according to a received burning instruction, control corresponding input terminals of the controllable switches to be connected to corresponding output terminals and also control an output terminal of the master controllable switch module to be connected to the corresponding input terminal. Obviously, a JTAG chain can be automatically adjusted by controlling the connection relationship between input and output terminals of the corresponding switches by only building a circuit, so that firmware burning on different chips or chip combinations is realized without manual adjustment, thereby improving the test efficiency, and simplifying the circuit structure.
