Enter end signal to for < SX,SX+2>, output end signal SX+3.Assuming that S1 and S3 are overturn simultaneously.Overturning can be led while S1 and S3
The overturning for causing S4, since S6 and S8 is not affected, S1 can be restored to original correct logic level, S2 and S8's
Correct logic level can also make S3 be restored to original correct logic level, and later, the recovery of S1 and S3 can make S4 extensive again
It is multiple.Finally, all nodes of circuit are original correct logic level.
The basic principle of latch circuit function described in the present embodiment:
1. break-through mode: when clock signal clk is high level, CLKB is low level.MC1, MC3, MC5, MC7 are in
Off state, output are high-impedance state.Data are incoming from input terminal D, by transmission gate TG1-TG4, reach in storage unit
Memory node S1, S3, S5 and output end Q (S7).
2. latch mode: when clock signal clk is low level, CLKB is high level.Transmission gate TG1-TG4 is closed,
MC1, MC3, MC5, MC7 are on state, at this point, the Muller C cell of 4 clock controls is functionally showed with MC2, MC4,
MC6, MC8 are identical.According to the relationship of latch, data are sustainedly and stably spread out of from output end Q (S7).
When clock signal clk is high level, CLKB is low level, and circuit is in break-through mode at this time, is stored when two
When mistake overturning occurs for node, error signal will not be stored, because input terminal D constantly has data incoming, mistake is quickly
Just refreshed, will not be latched.So consider that CLKB is high level, and circuit is in when clock signal clk is low level
Situation under latch mode.
Two bit flippings: two node potentials are flipped simultaneously.Node S1-S8 in storage unit can be divided into 28
It is right, wherein 8 classes can be summarized as again by their design feature:
(1)<S2X-1,S2X>:<S1,S2>,<S3,S4>,<S5,S6>,<S7,S8>;
(2)<S2X,S2X+1>:<S2,S3>,<S4,S5>,<S6,S7>,<S8,S1>;
(3)<S2X-1,S2X+1>:<S1,S3>,<S3,S5>,<S5,S7>,<S7,S1>;
(4)<S2X,S2X+2>:<S2,S4>,<S4,S6>,<S6,S8>,<S8,S2>;
(5)<S2X-1,S2X+2>:<S1,S4>,<S3,S6>,<S5,S8>,<S7,S2>;
(6)<S2X,S2X+3>:<S2,S5>,<S4,S7>,<S6,S1>,<S8,S3>;
(7)<S2X-1,S2X+3>:<S1,S5>,<S3,S7>;
(8)<S2X,S2X+4>:<S2,S6>,<S4,S8>.
Wherein 1≤X≤4, and X is integer.Enabling N is the integer less than 13, as N > 8, SN-8→SN(by SN-8Again it assigns
To SN)。
In the case where being low level (CLKB is high level at this time) due to CLK, the Muller C cell of clock control (MC1,
MC3, MC5, MC7) it can be equivalent to the Muller C cell (MC2, MC4, MC6, MC8) of no clock control, above 8 kinds of classification can be into one
Step is divided into following 4 class:
(1)<SX,SX+1>:<S1,S2>,<S2,S3>,<S3,S4>,<S4,S5>,<S5,S6>,<S6,S7>,<S7,S8>,<
S8,S1>;
(2)<SX,SX+2>:<S1,S3>,<S2,S4>,<S3,S5>,<S4,S6>,<S5,S7>,<S6,S8>,<S7,S1>,<
S8,S2>;
(3)<SX,SX+3>:<S1,S4>,<S2,S5>,<S3,S6>,<S4,S7>,<S5,S8>,<S6,S1>,<S7,S2>,<
S8,S3>;
(4)<SX,SX+4>:<S1,S5>,<S2,S6>,<S3,S7>,<S4,S8>.
Wherein 1≤X≤8, and X is integer.Enabling N is the integer less than 13, works as SN> S8When, SN-8→SN(by SN-8Again it assigns
To SN)。
The waveform diagram of each signal in Fig. 2 a latch circuit is shown as with reference to Fig. 3, Fig. 3.Waveform description: (1) to section
Point is to < SX,SX+1> verifying: in 6ns, transient error (transient fault, referred to as: TF) is applied simultaneously to S1 and S2
Pulse;In 12ns, transient error pulse is applied simultaneously to S3 and S4.(2) to node to < SX,SX+2> verifying: in 26ns
When, transient error pulse is applied simultaneously to S5 and Q (S7);In 32ns, transient error pulse is applied simultaneously to S6 and S8.(3)
