Occasional ContributorOn 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]);
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,
