Question

Explain lay out rules for 2 micro meter technology in vlsi design

Answer 1

Layout or Design Rules:Design rules specify geometric constraints on the layout artwork.Provide a communication channel between the IC designer and the fabrication process engineer.

 

Objective:To obtain a circuit with optimum yield.To minimize the area of the circuit.To provide long term reliability of the circuit.

 

Design rules represent the best compromise between performance and yield:More conservative rules increase yield.More aggressive rules increase performance.

 

Design rules represent a tolerance that ensures high probability of correct fabrication - rather than a hard boundary between correct and incorrect fabrication.

Layout or Design Rules:Two approaches to describing design rules:
