QQ一直不知道怎解决这个bug
只好来请教版上各位前辈^^ 拜托了
问题：
L25: error: Continuous assignment lval 'z' not a net
Finished Phase I
Process exited with code 0.
---------程式码---------------
module HW5_25(z,clk,rst,x,y);
input x,y,clk,rst;
output z;
reg [1:0]state;
reg z;
parameter s0=2'b00,s1=2'b01,s2=2'b10,s3=2'b11;
always@(posedge clk or negedge rst)
if(~rst) state <= s0;
else
case(state)
s0:if(x==0&&y==1) state <= s2;
s1:if(x==0&&y==1) state <= s2;
else if (x==0&&y==0) state <= s0;
else state <= s3;
s2:if(x==0&&y==0) state <= s1;
else if(x==0&&y==1) state <= s3;
s3:if(x==0&&y==0) state <= s1;
endcase
assign z = state[1]; ------就是这一行
endmodule
