Overflow Detection Simulator

← Back to Unit 1

Description

Explore how overflow occurs in signed binary arithmetic. See when adding or subtracting two's complement numbers produces incorrect results due to the limited range of representation.

Learning Objectives

Bloom Level: Analyze (L4)

After using this MicroSim, students will be able to:

• ✓ Detect overflow conditions in signed arithmetic
• ✓ Explain why overflow occurs when result exceeds representable range
• ✓ Apply overflow detection rules for addition and subtraction

How to Use

1. Select addition or subtraction operation
2. Adjust Value A and Value B sliders
3. Observe when the result overflows the 4-bit range
4. Study the overflow detection rules shown below
