跟C一样, Verilog区分大小写并且有一个基本的预处理(虽然比ANSI C/C++复杂度小很多). 它的流控关键词 (if/else, for, while, case, etc.) 是相当的,它的运算优先级与C兼容. 句法的差异表现在: required bit-widths for variable declarations, demarcation of procedural blocks (Verilog uses begin/end ...

Gray code counters (having one bit change per counter transition) are often used in FIFO design and digital communication. Here I will show two styles gray code counter. Style #1 First style gray code counter uses a single set of flip-flops as the Gray code register with accompanying Gray-t...
A binary counter is a simple counter that has an initial value of 0 at the time of reset. It value keeps incrementing by 1 at each clock cycle. And finally it reaches its maximum value, say 1111 in binary for a 4 bit counter, it again reaches 0000 in binary and keeps counting one...
Package and Libraries - allow designers to organize and reuse code across multiple projects. Packages can contain declarations of data types, subprograms, and components, while libraries are used to store and manage packages and design units. For example, consider a simple 4-bit counter implemented...
gray<=4'b0; end else begin gray<=gray_counter; end end endmodule Style #2 A second Gray code counter style, the one described below, uses two sets of registers, one a binary counter and a second to capture a binary-to-Gray converted value. The intent of this Gray code counter style...

图中Binary Stream为输入的二进制数据流,+/- code即为AMI码,可以看出所有的1都被表示成了+1和-1,在实际通信中,他们分别代表着高电平和低电平(例如+3.3v和-3.3v),也可以都代表高电平但使用两条数据通道传输(一条为+1和0,一条为-1和0),如下图所示: ...
