题目:The 7400-series integrated circuits are a series of digital chips with a few gates each. The 7420 is a chip with two 4-input NAND gates.Create a module with the same functionality as the 7420 chip. It has 8
Given four unsigned numbers, find the minimum. Unsigned numbers can be compared with standard comparison operators (a < b). Use the conditional operator to make two-waymincircuits, then compose a few of them to create a 4-waymincircuit. You'll probably want some wire vectors for the interm...
Dataflow modeling provides the descriptions of combinational circuits by their function rather than by their gate structure.*// module dflipflo (q, d_in, clk_in); / module defines d flip flop in data flow modelling input clk_in, d_in ; / input variable of the d flip flop output q; ...

Real hardware circuits inevitably have delays. In Verilog, you can describe the delay information of logic gates and transistors. You can specify a time for the delay of the component, and then use this time for the rise, fall, and shutdown delays; you can also specify the rise delay and...
To start with, we will be learning the design of simple combinational circuits using Verilog followed by more complex circuits. As we progress further, we will be designing sequential circuits. In Chapter 4, we will see how to write effective test benches so that we may test the ...
We will continue to learn more examples with Combinational Circuit - this time a full adder. A combinational circuit is one in which the present output is a function of only the present inputs - there is no memory. This is different from the sequential circuits that we will learn later ...
