Pvt corners in physical design

PVT is the Process, Voltage, and Temperature. In order to make our chip to work after fabrication in all the possible conditions, we simulate it at different corners of process, voltage, and temperature. These conditions are called corners.

What is PVT in physical design?

PVT is abbreviation for Process, Voltage and Temperature. In order to make our chip to work in all possible conditions, like it should work in Siachen Glacier at -40°C and also in Sahara Desert at 60°C, we simulate it at different corners of process, voltage and temperature which IC may face after fabrication.

What is PVT variation?

Variability into design comes due to process, voltage and temperature (PVT) variation is a naturally occurring phenomenon during the fabrication of an integrated circuit (IC) that deviates of transistor electrical characteristics from the expected value.

What is PVT variation in VLSI?

PVT is acronym for Process-Voltage-Temperature. PVTs model variations in Process, Voltage and Temperature. There's other term OCV which refers to On-Chip Variation.

What are corners in VLSI?

graph, but called a corner, anyway), fast-fast (FF), slow-slow (SS), fast-slow (FS), and slow-fast (SF). The first three corners (TT, FF, SS) are called even corners, because both types of devices are affected evenly, and generally do not adversely affect the logical correctness of the circuit.
