  • Area efficient clock inverting circuit for design for testability
    Patent number: 6529033
    Abstract: A method for fabricating IC devices including both rising edge-triggered circuits (e.g., flip-flops or latches) and falling edge-triggered circuits in which a clock signal line is selectively inverted by an on-chip clock signal inverting circuit and applied to one or the other circuit types during test modes. The clock signal inverting circuit is implemented as a two-input exclusive-OR gate, or using a multiplexer. The method includes placing and routing the selected circuit type (i.e., rising or falling edge) such that clock skew is minimized.
