The case statement walks down the list of cases and executes the first one that matches. Answer expected was to the point and concise Verilog scheduling semantics basically imply a four-level deep queue for the current simulation time: Since the "a = 0" is an active event, it is scheduled into the 1st "queue". When you are comparing 2 nos using "==" and if one/both the numbers have one or more bits as "x" then the output would be "X" . Wait five time units before doing the action for "a = b;". Question 2.
