Consider the following piece of VHDL code: LIBRARY IEEE; USE IEEE.STD_LOGIC_1164.ALL; ENTITY q4a IS END ENTITY q4a; ARCHITECTURE dataflow OF q4a IS SIGNAL a,b,c: STD_LOGIC: = '1'; SIGNAL d, e, f: STD_LOGIC; BEGIN a <= '1', '0' AFTER 10 NS; d <= a NAND b AFTER 10 NS; e <= b AND C AFTER 14 NS; f <= d XOR e AFTER 10 NS; c <= '1', '0' AFTER 14 NS; END ARCHITECTURE dataflow; Explain how the code is executed and how the event queue is modified as a result. Show the state of the event queue as time progresses through the simulation. Use your answer to show how the waveforms for each of the signals change with time. Comment on the key features of the waveforms.
