Implementing User-Defined "Wait For" time

Disclaimer: I'm a noob

I'm trying to implement an entity which takes as an input a 16-bit binary number called bounceWidth( in std_ulogic_vector(15 downto 0)) which will represent the time in which a pulse wave will last. In my behavioral architecture, I have a variable called intWidth ( in std_ulogic_vector(15 downto 0)) and another one called pulseWidth ( time ).

My desire is to convert the input into a valid form of time expressed in ns so as to be used with the "wait for" command.

Below is what I'm doing that Quartus doesn't like:

--- Quote Start ---

library ieee;

use ieee.numeric_std.all;

use ieee.std_logic_1164.all;

entity bounce_processor is

generic (prop_delay: Time:= 10ns);

port (clock: in std_logic;

bouncewidth: in std_ulogic_vector(15 downto 0);

bounceCount: in std_ulogic_vector(7 downto 0);

opcode: in std_ulogic_vector(2 downto 0);

start: in bit;

output: out bit);

end bounce_processor;

architecture behavioral of bounce_processor is

variable intwidth : integer range 0 to 65535;

variable intCount : natural range 0 to 10;

variable starting_output : bit;

variable pulsewidth : time;

begin

process(clock)

begin

if (rising_edge(clock) and start = '1') then

intwidth := to_integer(bouncewidth);

pulsewidth := time(intwidth);

intCount := to_integer(bounceCount);

starting_output := output;

if opcode = "000" then

output <= '0';

elsif opcode = "001" then

for i in 0 to intCount loop

output <= not output;

wait for pulsewidth ns;

end loop;

if starting_output = '1' then

output <= 0;

else

output <= 1;

end if;

elsif opcode = "010" then

output <= '1';

elsif opcode = "011" then

output <= '0';

end if;

end if;

end process;

end behavioral;

Any help would be greatly appreciated.
