Security Thorough VLSI Technology on Safer+

Power consumption is an interest of major debate these days, be it at a grand level like in Big Industrial application or at a small level like in Electronic Circuits. Now just about every day pretty much all the electronics devices contain VLSI chip(s). VLSI plays a beneficial role in the present day-to-day life of a global citizen.

Using the technical advancements when you look at the VLSI technology, technology node & hence circuit size keeps on shrinking. With smaller technology nodes, power consumption becomes an important parameter in just about any VLSI design. Smaller technology nodes, while helps in attaining a lower life expectancy footprint regarding the system, results in increased power consumption in each chip.

Any VLSI designer would understand that there are two forms of power consumption in virtually any Chip. A person is a static power (leakage) & another one could be the dynamic power (switching & short-circuit).

Dynamic power will get ingested when chip performs its described function(s). However, fixed power consumption occurs irrespectively of chip performing any helpful features.

Lower the static power usage of the chip, better it is from the PowerPoint of view.

Various techniques may be adopted to lessen the static power consumption in virtually any given design to execute a given collection of functionalities.

1. No overuse of technology: - If given functionality is certainly not demanding the utilization of the latest (smaller) technology node, the greater the amount of suitable technology node should always be used to fulfil the design needs. Remember, smaller the technology node, higher could be the static power consumption.

2. Operating at lower temperature: - As temperature regarding the VLSI chip increases, static power consumption increases (due to higher leakage current). Hence in virtually any system design, VLSI chips should always be operated at the lower temperature & not near to the maximum temperature specified because of the Chip vendor. The perfect case is always to operate the chip at near to the ambient temperature, whenever we can. Various thermal approaches to the device design may be adopted to make this happen.

3. Power shut a block: If a block isn't needed for a given operation as well as a given period, it must be power down to truly save static power in addition to dynamic power. Carrying this out operation adds some logic overhead & some complexity into the chip in design & layout, nonetheless it will probably pay off throughout the whole life course of the device with regards to of power conserving & increased reliability (as a result of less heat generation as a result of shutting the block if not being used) if justified by a target volumes regarding the Chip.

Exception for this should be those blocks which should be operated with greater regularity and shutting down & bringing it up might need complex protocols & training sequences etc. to be run for every single such operation.

Most of the above techniques are derived from the usages regarding VLSI technology & Chips. By using these techniques static power consumption can be reduced dramatically. Less power requirement can help in making use of a smaller battery for portable device applications. These techniques could also end up in reduced device cost.
