Implement D flip-flop with a couple of latches? Write a VHDL
Code for a D flip-flop?

Answer Posted / balaji

library ieee;
use ieee.std_logic_1164.all;

entity d_ff is
port(d,clk:in std_logic;
q,q'bar:out std_logic);
end d_ff;

architecture a_d_ff of d_ff is
begin
process(clk)
begin
if rising_edge(clk) then
q<=d;
q'bar<=not d;
end if;
end process;
end a_d_ff;

Calculate rise delay of a 3-input NAND gate driving a 3-input NOR gate through a 6mm long and 0.45m wide metal wire with sheet resistance R = 0.065 / and Cpermicron= 0.25 fF/m. The resistance and capacitance of the unit NMOS are 6.5k and 2.5fF. Use a 3 segment -model for the wire. Consider PMOS and NMOS size of reference inverter as 2 and 1 respectively. Use appropriate sizing for the NAND and NOR gate.
