CLKFX_DIVIDE是1到32之间的整数值.VLDL和Verilog都有一个示例实例化模板。请注意，当前Spartan系列（-3...
关于以下分频器程序中,clk为系统时钟,则该分频器的分频数是多少?输出信号的占空比是多少?always@ (posedge clk) begin if (divider==M) begin carry<=1; divider<=P; end else begin divider<=divider+1; carry<=0; end end? 1/M-P+1 1/M-P1/M-P;; 1/M-P+11/M-P; 1/M-P1/M-P+1 1/...
port map (O => clk4,-- Clock buffer outputI => clk3 -- Clock buffer input);我用这个map的时候却总是报错DCM_SP symbol "DCM_SP_inst1" (output signal=clk3) has anequation that uses input pin I0,which no longer has a connected signal....
