CMOS电路中的逻辑门有非门、与门、与非门、或非门、或门、异或门、异或非门,施密特触发门、缓冲器、驱动器等与非门则是当输入端中有1个或1个以上是低电平时,输出为高电平;只有所有输入是高电平时,输出...与非门(英语:NAND gate)是数字电路的一种基本逻辑电路。若当输入均为高电平(1),则输出为低电平(0);...

从上图可以看出,Verilog适合系统级(system)、算法级(alogrithum)、寄存器传输机(RTL)、逻辑级(logic)、门级(gate)、电路开关级(switch)的设计,而System Verilog是Verilog语言的扩展和延伸,更适合于可重用的可综合IP和可重用的验证用IP设计,以及特大型(千万门级以上)基于IP的系统级设计和验证。 与传统的电路原理图...
Build an AND gate using both an assign statement and a combinational always block. (Since assign statements and combinational always blocks function identically, there is no way to enforce that you're using both methods. But you're here for practice, right?...) ...

electronic functional verification. Supporting both SystemVerilog and very high-speed integrated circuit hardware description language (VHDL), it’s ideally suited for application-specific integrated circuits (ASICs) and field-programmable gate arrays (FPGAs), offering a robust solution for advanced design...
The next interesting structure is a transparent latch; it will pass the input to the output when the gate signal is set for “pass-through”, and captures the input and stores it upon transition of the gate signal to “hold”. The output will remain stable regardless of the input signal ...
