sequential (22) no realistic serial circuit (the register of If-Else)

John: The 1st picture is a simple If-Else's register. Both the value of Ca and Ba enter the Xor gate. . If (Xor gate = true) { Cv = Bv } Me: Ok. John : Of the 2nd and 3rd Picture, which picture is logical. Me: The 2nd picture is logical. Why? When the Clk line of RJ45 is at up cycle, the Clock input of CV, CA, BV, BA are at up cycle. John: You are wrong. When the clock line of RJ45 is at up cycle, the Clock input of BV, BA, CV are at Up Cycle. But, the clock input of CA is at down cycle. . Me: How can it be ? . John : Hackers hack the Clock line of RJ45. Eventually, it become, . If (Xor gate = true) { Cv isn't equal to BV. }
