  • Scan cell including a propagation delay and isolation element
    Patent number: 6412098
    Abstract: In an integrated circuit, a scan cell has a data input terminal, a data output terminal, a scan enable terminal a scan output terminal, and a clock input terminal. A multiplexer in the scan cell has a first input terminal connected to the data input terminal, a second input terminal connected to a scan input terminal, a control terminal connected to the scan enable terminal, and a multiplexer output terminal. A D-type flip-flop element in the scan cell has a data input terminal connect to the multiplexer output terminal; a clock terminal connected to the scan cell clock input terminal; and a data output terminal connected to the scan cell data output terminal. An AND gate in the scan cell has a first terminal connected to the scan enable terminal, a second terminal coupled to the data output terminal of the D-type flip-flop, and an output terminal connected to the scan output terminal.
