Hi,

The following lines has a print value: 1431655761, while the picture shows that it is 21841.





Code:
[COLOR="#0000CD"]


integer intA;
reg [15:0] regA;

intA = -4'd12 / 3;
$display ("\$display: A4 = %b, A4 = %d", intA, intA); // 

step
# $display: A4 = 01010101010101010101010101010001, A4 =  1431655761[/COLOR]

What is wrong? My code or the description?

Thanks,

integers are always 32-bits.

Try this out.
Code:
module test1 ();

integer intA;
reg [15:0] intB;
reg [15:0] regA;

initial begin
  intA = -4'd12 / 3;
  intB = -4'd12 / 3;
  $display ("\$display: A4 = %b, A4 = %d", intA, intA); // 
  $display ("\$display: B4 = %b, B4 = %d", intB, intB); // 
end

endmodule

If the value is correctly defined as 16 bits you get the answer in the picture.

Regards
