配置就不用说了,看“PLL配置详细说明.pdf”即可。
测试文件如下:
`timescale 1 ns/ 1 ns
module PLL100_vlg_tst();
reg eachvec;
reg areset;
reg inclk0;
wire c0;
wire locked;
PLL100 i1 (
.areset(areset),
.c0(c0),
.inclk0(inclk0),
.locked(locked)
);
initial
begin
$display("Running testbench");
end
initial
begin
inclk0=0;
forever #12.5 inclk0=~inclk0;
end
initial
begin
areset=0;
#1000 areset=1;
#2000 areset=0;
#3000 $stop;
end
always
begin
@eachvec;
end
endmodule
