Method of designing and making an integrated circuit |
摘要 |
A method of transforming a first integrated circuit design comprising a plurality of D-type flip-flops each having a clock signal and being associated with an enable signal into a second integrated circuit design using guard-flops, the method comprising: identifying D-type flip-flops in the first integrated circuit design, and transforming each of the identified D-type flip-flops into a guard-flop comprising a transparent catch latch and a transparent pass latch; generating a catch enable signal for controlling the transparent catch latch from the clock signal and enable signal of the D-type flip-flop in the first integrated circuit design; and generating a pass enable signal for controlling the transparent pass latch based on the catch signals of at least some of the guard-flops that take data from the D-type flip-flop in the first integrated circuit design.
