Reply To: How to compare compare std_logic and integer

[Jim Lewis]

Hi Steve,

CoveragePkg contains a to_integer function for both std_logic and boolean.  So your assertion is no more than:

  signal sig_std_logic : std_logic ;
  signal sig_integer : integer ;
  . . .
  if to_integer(sig_std_logic) = sig_integer then

OTOH, if you are trying to compare a std_logic_vector, use the to_integer function from  package, ieee.numeric_std_unsigned.

The following shows a way to randomize a value between 0 and 1 in std_logic:

TestProc : process

  variable RV : RandomPType ;
  variable B_sl : std_logic ;
begin
  (0 => B_sl) := RV.RandSlv(0, 1, 1) ;

Best, 

Jim
