Takes two signed integers and returns the most positive of the two, or
in_A if equal. For example:
Bring in the function at the start of the body of your module like so:
Pass the function a value which, at elaboration time, is either a constant or an expression which evaluates to a constant. Then use that value as an integer for a localparam, genvar, etc...
This function is handy when you have words of different parameterized widths and you want to scale then all to the width of the largest word (see: Width Adjuster).
function integer max; input integer in_A; input integer in_B; begin if (in_A >= in_B) begin max = in_A; end else begin max = in_B; end end endfunction
