Wrong is NOT Always Illegal
• In Networks-on-Chip, checking for legality is the same as checking for correctness.
Let the values be wrong. As long as they are legal…
• But checking for legality is much simpler• Extremely fast and efficient fault detection• Instantaneous detection

Invariance Checking
• How to achieve this: Invariance Checking• Inputs and outputs of the main components are constantly
monitored
• Extremely lightweight solution• 3% Area Overhead• 0.7% Power Overhead• 1% Delay Overhead
• Scales efficiently to more complex designs
