Digital System Projects Using HDL Questions and Answers
The Digital System Projects Using HDL questions with answers section focuses on VHDL and Verilog-based digital design. These programming questions and answers are ideal for ECE students preparing for hardware design roles or competitive exams. You’ll learn about combinational and sequential circuits, FPGA implementation, and simulation testing through well-explained MCQs. Practicing these helps you understand how HDL languages model real hardware systems, a key skill for interviews at Intel, DRDO, and TCS Electronics divisions.

1. In a frequency counter, what happens at high frequencies when the sampling interval is too long?
- The counter works fine.
- The counter undercounts the frequency.
- The measurement is less precise.
- The counter overflows.
2. In the digital clock project, when does the PM indicator go high?
- Never
- Going from 11:59:59 to 12:00:00
- Going from 12:59:59 to 01:00:00
- On the falling edge of the clock after enable goes high
3. How is the output frequency related to the sampling interval of a frequency counter?
- Directly with the sampling interval
- Inversely with the sampling interval
- More precision with longer sampling interval
- Less precision with longer sampling interval
4. In an HDL application of a stepper motor, after an up/down counter is built what is done next?
- Build the sequencer
- Test it on a simulator
- Test the decoder
- Design an intermediate integer variable
5. In a digital clock application, the basic frequency must be divided down to:
- 1 Hz.
- 60 Hz.
- 100 Hz.
- 1000 Hz.
6. In the keypad application, what does the data signal define?
- The row and column encoded data
- The ring encoded data
- The freeze locator data
- The ring counter data
7. What does the ring counter in the HDL keypad application do when a key is pressed?
- Count to find the row
- Freeze
- Count to find the column
- Start the D flip-flop
8. In the digital clock project, the purpose of the frequency prescaler is to:
- find the basic frequency.
- transform a 60 pps input to a 1 pps timing signal.
- prevent the clock from exceeding 12:59:59.
- allow the BCD display to have a value from 00–59.
9. Which is not a step that should be followed in project management?
- Overall definition
- System documentation
- Synthesis and testing
- System integration
10. In the keypad application, what does the preset state of the ring counter define?
- The proper output of the column encoder
- The NANDing of the rows
- The NANDing of the columns
- The proper output of the row encoder
