LAB#5
SIMULATION TEST BENCH OF 6 BIT SUBTRACTOR
I. Objective
The objective is to learn writing a Test Bench for a 6-bit subtractor. You will
simulate your design using ModelSim and write a test bench for obtaining the simulation
results.
II. Instructions
!Read section 2.19, Page 119 Text Book for example on how to write Test Bench
!Revise Class notes
!Create a test bench for the 6-bit subtractor from lab 2
!Provide 5 test samples to the subtractor and check the outputs
III. Deliverables
1. Demonstration is required
2. Pre- Lab: No Pre-Lab is required.
3. Report:
a. Objective
b. Lab work:
– Implementation: describe your design
– Print and report the results including your codes
c. Conclusion: What went wrong? Why? , And how did you solve it?
