急求找錯误

整多两支XO

我的下面代码哪里错了呢？存储器讀的功能没有实現啊！急着用，幫忙看看吧，谢谢了！


   

         

            
module multi_modular_ram(data1,data2,read,write,addr);

input read,write;

parameter addr_bits=8,wordsize=8,words=(1<<addr_bits);

input[8:0] addr;

inout[7:0] data1,data2;

reg[7:0] data1,data2;

reg[7:0] myram1 [0:255];

reg[7:0] myram2 [0:255];

wire[7:0] addre1,addre2;

initial

begin



$readmemb("ram_data.txt",myram1);



$readmemb("ram_data.txt",myram2);

end

assign  addre1=addr[7:0];

assign  addre2=addre1+1'b1;

always @(read)

begin





if(addr[8]==1)



begin



data1=read?myram2[addre1]:8'bz;



data2=read?myram2[addre2]:8'bz;



end



else if(addr[8]==0)



begin



data1=read?myram1[addre1]:8'bz;



data2=read?myram1[addre2]:8'bz;



end

end



always @(posedge write)



begin

if(addr[8]==1)



begin



myram2[addre1]=data1;



myram2[addre2]=data2;



end



else if(addr[8]==0)



begin



myram1[addre1]=data1;



myram1[addre2]=data2;
