What is parasitic in VLSI?

In electrical networks, a parasitic element is a circuit element (resistance, inductance or capacitance) that is possessed by an electrical component but which it is not desirable for it to have for its intended purpose.

What are RC corners in VLSI?

Delay at W1 > Delay at W < Delay at W2, Your wire lies across the W-opt in the graph. This explains how delays of wires changes across RC corners. We have 4 RC interconnect corners: Cmin, RCmin, Cmax, RCmax.

What do you mean by parasitic extraction?

In electronic design automation (EDA), parasitic extraction (PEX) is calculation of the parasitic effects in both the designed devices and the required wiring interconnects of an electronic circuit: parasitic capacitances, parasitic resistances and parasitic inductances, commonly called parasitic devices, parasitic …

What are parasitic properties?

A parasite is an organism that lives in another organism, called the host, and often harms it. It depends on its host for survival. Without a host, a parasite cannot live, grow and multiply. For this reason, it rarely kills the host, but it can spread diseases, and some of these can be fatal.

What is PEX in cadence?

This section describes how to extract a netlist from your layout that includes parasitic resistances. and capacitances. You will then be able to re-simulate your design with extracted parasitics in Spectre. PEX requires a clean LVS so that extracted parasitics can be correlated to nets on the schematic.

What are parasitic corners?

Refers to corners which results maximum Capacitance. So also known as Cmax corner. Interconnect resistance is smaller than at typical corner. This corners results in largest delay for paths with shorts nets and can be used for max-path-analysis.

What is circuit extraction in VLSI?

From Wikipedia, the free encyclopedia. The electric circuit extraction or simply circuit extraction, also netlist extraction, is the translation of an integrated circuit layout back into the electrical circuit (netlist) it is intended to represent.

What are the 3 types of parasites?

There are three main classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.

What is post layout simulation and parasitic extraction?

Post Layout Simulation. The parasitic capacitances extracted according to how your layout is designed might be critical in affecting the actual performance of your design. In order to get an idea of how the design would work from your layout, you should perform a post-layout simulation from the extracted view.

What is Calibre xACT?

The Calibre xACT platform provides designers with a fast, highly accurate, and multi-purpose parasitic extraction tool that enables post-layout simulation across a wide range of designs and advanced process nodes.
