    • The present invention is a method and apparatus that initializes N-NARY logic and dynamic logic to a special stress mode. The present invention has a logic circuit that includes a shared logic tree with one or more evaluate nodes, one or more precharge devices, and an evaluate device. Coupled to the evaluate nodes is a state generation control circuit that generates a state signal. A state generation circuit receives the state signal from the state generation control circuit and initializes the evaluate nodes to a functionally illegal state that initializes the logic circuit to the special stress mode. One embodiment of the present invention initializes the evaluate nodes to a low state. When the first logic circuit in a series of logic circuits is initialized to the functionally illegal state, the present invention will initialize the succeeding logic circuits in the series as each phase in the different clock domains evaluate, which initializes the succeeding logic circuits to the special stress mode.

    • A gated clock driver is configured to provide an enable signal and a gated clock signal at each of a plurality flip-flops. One of the p-channel transistors of the gated clock driver's NOR gate is distributed to each of the flip-flops or latches in the system. Additionally, an extra n-channel transistor is provided in the gated clock circuit to form an inverter with the nondistributed p-channel transistor. More particularly, the p-channel transistor that is driven by the system clock input is distributed to each of the flip-flops. Similarly, the enable input (at the output of the new inverter) is distributed to each of the flip-flops. Since the gated clock signal cannot be generated without the enable signal being high and the system clock being low, distributing enable and the p-channel transistor which receives the system clock as an input minimizes clock skew as compared to flip-flops with a completely shared clock gating clock.
    • 门控时钟驱动器被配置为在多个触发器中的每一个提供使能信号和门控时钟信号。 门控时钟驱动器的或非门的p沟道晶体管之一被分配到系统中的每个触发器或锁存器。 此外,在门控时钟电路中提供了额外的n沟道晶体管,以形成具有非分布式p沟道晶体管的反相器。 更具体地,由系统时钟输入驱动的p沟道晶体管被分配到每个触发器。 类似地,使能输入(在新的反相器的输出处)被分配给每个触发器。 由于门控时钟信号不能在没有使能信号为高电平且系统时钟为低的情况下产生,所以与具有完全共享的触发器相比,接收系统时钟作为输入的分配使能和p沟道晶体管使时钟偏移最小化 时钟门控时钟。
