Verilog 上升沿与下降沿检测
摘要:
FPGA中常用的上升沿检测和下降沿检测代码,使用的verilog hdl语言//上升沿检测module pose_chk(clk, in, out);input clk, in;output out;reg curr, last;always@(posedge clk)begin curr <= in; last <= curr;endassign out = curr & (~last);endmodule//下降沿检测module nege_chk(clk, in, out);input clk, in;output out;reg curr, last;always@ 阅读全文
