What are Tap Cells in VLSI (1)

When it comes to VLSI design, understanding the role of every component is crucial. One such component that often flies under the radar but is integral to VLSI chips is the tap cell. So, exactly what are tap cells in VLSI? and why should you care about them?

What are tap cells in VLSI?

1. The Foundation of Power Distribution

Imagine a VLSI chip as a bustling metropolis, and tap cells as the power distribution hubs. They are strategically placed to ensure that electricity flows seamlessly, much like how a well-planned transportation network keeps a city running smoothly.

2. Voltage Vigilantes

One of the tap cell’s primary tasks is to maintain a consistent voltage across the chip. Think of it as the chip’s vigilant guardian against voltage fluctuations. It steps in to boost voltage when needed, preventing any hiccups in chip performance caused by voltage drops.

3. Ensuring Equal Access

Tap cells ensure that every part of the chip gets equal access to power and maintains a stable ground connection. This equitable distribution is vital, preventing certain chip areas from being starved of power or experiencing ground-related issues.
