What is the role of ERC in VLSI?

ERC stands for Electrical Rule Check.

It checks all possibilities of Electrical connection between all layers according to the technology node.

Reasons for ERC check.

Its checks…

• If we short the output
• It checks any Floating devices, gates, pins, and nets
• If any input is left unconnected,
• Floating wells
• If any gates are connected directly to supplies,
• If the design includes any possible ESD damage, etc.
• Connecting high voltages to the thin gates
• Minimum n-well widths
• Any floating layers
• Wrong overlap of P-plus or N-plus

What is ERC in the circuit?

An electrical rule check (ERC) ensures that integrated circuits function correctly. ERC tools can detect potential circuit errors that could lead to reduced yields or circuit malfunctions after delivery. ERC ensures the functionality, reliability, and manufacturability of PCBs.
