If high leakage by adding Antenna cell, what to do? Can jogging to upper layers cause new antenna violations? How floating cell addition helps in antenna fixing any disadvantages of it?

o   High Leakage from Antenna Cells: Antenna cells typically contain protection diodes connected to the input pins. These diodes, even when reverse-biased during normal operation, contribute a small amount of junction leakage current. If many antenna cells are added throughout the design, this cumulative leakage can become significant, especially in low-power designs.

o   Use jogging to upper layer: If resources available, can be routed to upper layer to reduce antenna effect on lower layer. Routing on upper layer may or may not cause new antenna violations depending on what is cumulative metal area of upper layer.

o   Floating Cell Addition for Antenna Fixing? Adding a floating cell, with input connected to gate with antenna violation and output floating can help in antenna violation by increasing gate area.

This can increase the load on the net and may impact the timing.
