This can be translated into Verilog code: if (sel == 1) f = a; else f = b; Now before we go any further, we'll just take this code snippet a line at a time. if (sel == 1) The Verilog language allows for many different kinds of sequential statement. The procedural assignment ...
This implies that your Verilog code describes how data is transformed as it is passed from register to register. ... RTL code also applies to pure combinational logic - you don't have to use registers. To show you what we mean by RTL code, let's consider a simple example. What is ...
Verilog函数类似于软件函数(C或Pascal),是从表达式中调用的。函数接受一个或多个参数(输入)并返回一个结果。一个可以为字节范围的数据生成奇偶校验的可重用函数的例子如下所示。 示例2-5函数调用 DATA_OUT[6:0]=DATA_IN[6:0];DATA_OUT[7]=par_gen_func(DATA_IN[6:0]); ...
