Agenerateblock allows to multiply module instances or perform conditional instantiation of any module. It provides the ability for the design to be built based on Verilog parameters. These statements are particularly convenient when the same operation or module instance needs to be repeated multiple ti...
【Verilog我思我用】-generate 在使用xilinx官方例程《XAPP585》实现CameraLink接口发送或者接收数据时,有个程序还是值得学习的,下面把这段程序截出来: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 genvar i;genvar j;generatefor(i=0;i<=(N-1);i=i+1)begin:loop0...
http://stackoverflow.com/questions/22200666/problems-with-wires-declared-inside-verilog-generate-blocks Within agenerateblock, I have multipleifstatements. When I declare a wire in the first if statement - I can't use it in otherifstatements ...
genvari;generatefor(i=0;i<4;i=i+1)begin :gen_blockmy_module u_my_module (.in (input_signals[i]),.out (output_signals[i]));endendgenerate 2,创建多个连续赋值语句。genvar变量可以灵活的改变实例化模块的数量和连接方式,生成语句在综合过程中会被展开为实际的硬件电路。
