if in C on a Nios ? 

if in VHDL ? if in Verilog ?  Is the "if" in HDL and is it inside a clocked process/always block ?

[Altera_Forum]

is in verilog and is in a clocked always block. How can i execute the if instruction just once?

[Altera_Forum]

It will be executed every time the clock comes. 

 The only way to avoid it is to remember that it was already ran once:  logic once = 1'b0;  always @ (posedge clk) begin  if (once == 1'b0) begin  // insert your code here  once <= 1'b1; // remember that it already ran once  end end
