Strange behaviour with LEDs, 1 means LED off and 0 means LED on

Hello,

I have a development board with an EP4CE6E22C8 FPGA.

I have the following verilog code in Quartus Prime:

module Test(out);

output [7:0] out;
assign out = 8'b00111100;

endmodule 

The pin planner has been configured as pointed by the schematic. The problem is that 0 means on and 1 means off. I think this is a strange behaviour since the typical one is 1=on and 0=off.

Anybody knows if there is any option (in pin planner, quartus prime or whatever) to change this behaviour?

Thanks.
