verilog 中编译错误：port must be connected to a structural net expression
module counter8(clk,clr,te,le,a,tf);
input clk,te,le,clr;
input [7:0] a;
output [7:0] tf;
reg [7:0] tf,th;
regth u1(le,a,th);
count u2(clk,clr,te,th,tf);
endmodule
module regth(le,a,thout);
input le;
input [7:0] a;
output [7:0] thout;
reg[7:0] thout;
always@(le)
begin
if(le==1) thout
verilog 中编译错误：port must be connected to a structural net exp
你的th在counter8中定义为reg类型,而在regth中thout是一个输出信号默认为net类型,所以你在counter8模块中将th传给regth模块的thout就会报这样的错误,模块counter8中th信号只是一个模块之间的连线,所以定义成wire类型应该就可以了.
求解这段verilog语句中的编译错误 ___theory must be closely connected with practice is a basic verilog中a verilog中b[a-: 英语翻译To update this item,you must be connected to the device be connected to的同义词 be connected to 啥意思 在安装安卓SDK模拟器中,出现错误提示：A target must be selected in order to cr 是be connected with 还是be connected to A good system must be one every link is closely connected.Wh verilog HDL中这个错误是什么意思? be connected with 和 be connected to 和 be connected by的区别
