求高手来看看程序,急
我所写的程序
module prioritylineup(a,b,c,aout,bout,cout);
input a,b,c;
output aout,bout,cout;
if(a)
begin
aout=1; bout=0; cout=0; end
else if(!a&&b)
begin aout=0; bout=1; cout=0; end
else if(!a&&!b&&c)
begin aout=0; bout=0; cout=1; end
else if(!a&&!b&&!c)
begin aout=0; bout=0; cout=0; end
endmodule
调试时一直报有两个错
Error (10170): Verilog HDL syntax error at prioritylineup.v(4) near text "if"; expecting an identifier ("if" is a reserved keyword ), or "endmodule", or a parallel statement
Error (10112): Ignored design unit "prioritylineup" at prioritylineup.v(1) due to previous errors
求教如何改正,谢谢 verilog 的if,else 等一般写在 always 语句里面
纯逻辑的话,一般用assign 对,纯逻辑,要用assign. 表示连接到网线上,如果你用always做纯逻辑,也可以。但不可以单独的写ifelse作为模块 module test(
input wire a,
input wire b,
input wire c,
output wire aout,
output wire bout,
output wire cout,
);
assignaout = a?1‘b1:0;
assignbout = (!a&b)?1‘b1:0;
assigncout = (!a&!b&c)?1'b1:0;
endmodule 楼上这样写,实际上敢这么用吗
