What are antenna rules and how to fix antenna violations?

Question

Accepted Answer

Antenna rules are guidelines to prevent signal interference in integrated circuits. Antenna violations can be fixed by various techniques.

Antenna rules are design guidelines to prevent the formation of unintentional antennas in integrated circuits.
These rules aim to minimize the risk of signal interference and ensure reliable circuit operation.
Antenna violations occur when certain design features or structures unintentionally act as antennas, causing signal integrity issues.
To fix antenna violations, designers can employ techniques such as adding shielding layers, adjusting metal layer spacing, or modifying the circuit layout.
By following antenna rules and implementing appropriate fixes, the risk of signal interference can be minimized, improving overall circuit performance.

Accepted Answer

Antenna effects are parasitic effects which can be avoided by detouring the net.
