DE2-70 SOPC SDRAM compile error

Hi. 

 

I study with DE2-70 & "using the sdram memory on altera's de2-70 board 

with verilog design" manual. 

 

I practiced sopc & sdram example but i had some error messages as shown in the attached image. 

 

I assigned the pin map by importing "de2-70 pin assignments.csv" file, 

and coded verilog source file using pin node name. 

 

please let me how can i solve this problem.. 

 

Thanks in advance.

I do not programm in Verilog, but from my understanding the datapins should be bidirectional?! (you can read it in the sopc description: "dq to and from the...") I think the instanciation for that in verilog is "inout [15:0] dram_dq;" perhaps give it a try, but I am not sure. 

 

Have a nice day, Peter.

I didn't find my mistake about "inout" & "input".. 

Thanks for your apply!
