Question 1.
What is the primary purpose of simulation in digital circuit design?
Show hintHide hint
Think about the process before building circuits.
Question 2.
Define a testbench.
Show hintHide hint
Consider its role in testing circuits.
3Question 3.
What is the main benefit of using simulation before implementing on FPGA?
- It saves time and costs.
- It guarantees a perfect design.
- It avoids all errors.
Show hintHide hint
Think about the advantages of pre-testing designs.
4Question 4.
True or False: A testbench can only be written in VHDL.
- True
- False
Show hintHide hint
Consider the different hardware description languages available.
Question 5.
Design a comprehensive testbench for a 4-bit adder that includes corner cases such as maximum values and inputs with carry. Explain the logic behind each test case.
Show hintHide hint
Consider how carries affect outputs during addition.
Question 6.
You notice that upon running your simulation, an output does not match the expected result. Outline the steps you would take to troubleshoot this issue.
Show hintHide hint
Think about the design's logic and simulation inputs closely.
