If “clk” and “clear” are two inputs of a counter module, which of the following event expressions must be used if we want to implement asynchronous clear (assuming “clear” is active low, active high edge of “clk” signal is used for counting, and single “always” block is used for the implementation)?

None of the above

Suspend simulation

It cannot be determined exactly how many times the value of ‘x’ will be printed

The simulation will print the current value of ‘x’ 15-times

The simulation will print the current value of ‘x’ 13-times

The simulation will always display 15 as the value of ‘x’

A. 6’b111000

B. 6’b011000

C. None of the above

D. 6’b111111

A. 00100110

B. 00111110

C. 01111110

D. None of these

All of the above

A variable index used at the RHS of an “assign” statement generates a multiplexer whereas usage of it at the LHS results in a decoder

The “assign” statement can be used to implement both combinational as well as sequential circuits

The use of conditional operator in an “assign” statement always results in a multiplexer
