Answer A: The propagation delay are determined by the product datasheet 2.5V specification table. c <= a AND b AFTER 10 ns; -- same tphl and tplh-- If we need different propagation delays: IF a = '1' AND b = '1' THEN c <= '1' AFTER 9 ns -- tplh ELSE c <= '0' AFTER 10 ns -- tphl END IF; Jim Duckworth, WPI 12 Test Benches - Module 8a Adding Propagation Delays (cont’d) • This is called the Inertial Delay Model (default)
LOW again, the output of the NAND gate goes HIGH after the turn-off delay time tPLH. The typical turn-off delay time for a standard series TTL NAND gate is 11 ns. The average propagation delay time tp is then defined by: tp = (tPHL + tPLH) / 2. The maximum value for both tPHL and tPLH is 15 ns. Figure 3.4 Propagation Delay Times.

THERMOCHIP GYPSUM PLASTERBOARD (TPLH) is made up of a waterproof fibreboard plank, an extruded polystyrene core (different widths depending on the insulation needed) and a gypsum plasterboard plank on its interior side. Moreover, the TPLH finish has sharpened edges for a better application of the joint paste in order to join the panels together.
