A XOR gate logically acts as follows: if two input lines have equal values, the output will be zero and if two input lines have different values, the output equals 1. Therefore, this gate has several functions. Fig. 4(a) shows logical implementation of XOR and Fig. 4(b) indicates impl...
1)truth table,最straightforward的方式。 2)input scanning,根据门电路的control bit进行控制,AND由"0"控制,OR由"1"控制。 3)Parallel gate evaluation,通过计算机32Bit或64bit的多位计算,来进行bitwise parallel simulation。 Timing model: 1)transport delay,指gate input输出到gate output上的延时,norminal delay...
