On board 2 bit input

Hello, I have the MAX 10 DE-LITE board and im trying to create for example a simple mux on a hardware level so i can run it on the board. So after creating a GOLDEN TOP sv file my problem is how can i call my module with the correct on pin boards?

This is my module

module Task2 ( input clk50,
input logic sel [1:0],
output logic y);
logic clk05s,clk1s,clk2s,clk5s;
logic maxCnt05s = 12500000;
logic maxCnt1s = 25000000;
logic maxCnt2s = 50000000;
logic maxCnt5s = 125000000;
longint cnt05s,cnt1s,cnt2s,cnt5s;
initial
begin
cnt05s = 0;
cnt1s = 0;
cnt2s = 0;
cnt5s = 0;
clk05s <= 1'b0;
clk1s <= 1'b0;
clk2s <= 1'b0;
clk5s <= 1'b0;
end
always@(clk05s or clk1s or clk2s or clk5s or sel)
case (sel)
2'b00 : y = clk05s;
2'b01 : y = clk1s;
2'b10 : y = clk2s;
2'b11 : y = clk5s;
endcase
always@(posedge clk50)
if (cnt05s < maxCnt05s) cnt05s++;
else
begin
cnt05s=0;
clk05s<=!clk05s;
end
always@(posedge clk50)
if (cnt1s < maxCnt1s) cnt1s++;
else
begin
cnt1s=0;
clk1s<=!clk1s;
end
always@(posedge clk50)
if (cnt2s < maxCnt2s) cnt2s++;
else
begin
cnt2s=0;
clk2s<=!clk2s;
end
always@(posedge clk50)
if (cnt5s < maxCnt5s) cnt5s++;
else
begin
cnt5s=0;
clk5s<=!clk5s;
end
endmodule

So on the GOLDEN TOP sv file how can i call it?

Task2 try1(MAX10_CLK1_50,ARDUINO_IO[9]_ARDUINO_IO[8],ARDUINO_IO[7]);
I have tried it other ways for example like that ARDUINO_IO[9] : ARDUINO_IO[8],
or ARDUINO_IO[9]-ARDUINO_IO[8] and ofc it didnt work!

Basically my input for the sel [1:0] is arduino_io [9] and arduino_io[8].
I found how to do it on the pin planner but im just curious to see how it works there.
Thanks in advance

    Hi,


    The error occurs because of this line input logic sel [1:0], in Task2 module due to unpacked array.

    Have to change to packed array input logic [1:0] sel,


    Thanks,

    Best Regards,

    Sheng

    Need to see your top-level code, but a correct instantiation would be something like:

    Task2 try1 (MAX10_CLK1_50,{ARDUINO_IO[9],ARDUINO_IO[8]},ARDUINO_IO[7]);

    Curly brackets are concatenation.

    Also note that initial blocks are not synthesizable. You should have a reset control signal and use that to reset all those counters.

      Thank you for your time.

      Im getting this error
      Error (10928): SystemVerilog error at DE10_LITE_Golden_Top.v(136): packed array type cannot be assigned to unpacked array type - types do not match

      and this one

      Error (10716): SystemVerilog error at DE10_LITE_Golden_Top.v(136): can't pass value from actual to formal input "sel" with incompatible type

      Same with the answer from Sheng

    Hi,


    Or like below also get same result

    Task2 try1 (

    .clk50(MAX10_CLK1_50), .sel({ARDUINO_IO[9], ARDUINO_IO[8]}), .y(ARDUINO_IO[7])

    );


    Thanks,

    Best Regards,

        You would need to show your top-level code to understand why the I/O is not matching the sel data type.
