标题: QuartusII中编译出现的问题，求助！！ [打印本页] 作者: jiayanfu 时间: 2009-8-10 09:51 标题: QuartusII中编译出现的问题，求助！！ 请大家帮我分析一下我的程序中的错误，万分感谢！！
我想对memory型变量进行操作。
下面是我的程序：
module xinsuoyin (dataa,result);
input[5:0] dataa;
output[9:0] result;
reg[9:0] ramzhong;
reg[9:0] result;
reg[6:0] i;
(*ram_init_file = "cpu_ic_tag_ram.mif"*) reg [9:0] ram[63:0];
always@(dataa)
begin
for(i=0;i<=63;i=i+1)
begin
ramzhong[9:0]=ram;
if(ramzhong[9:4]==dataa[5:0])
begin
result[3:0]=ramzhong[3:0];
result[9:4]=6'b0;
end
end
end
endmodule
