The Verilog reduction operators are used to convert vectors to scalars. They operate on all of the bits in a vector to convert the answer to a single bit. The logic performed on the bit-vectors behaves the same way that normal AND, NAND, OR, NOR, XOR, and XNOR Gates behave inside of an FPGA.

I'm designing a circuit using Logisim that I will later physically implement. Unfortunately, the gates provided to me in the physical implementation do not include one of the gates I used in my design, namely a 4-input NAND. I do, however, have access to both 2- and 3-input NANDs.

Especially, the work is focused NAND gate on reduction of power dissipation, which is showing the effect of transient fault on selected NMOS transistor and PMOS transistor duplication and scaling connected to the same input.

A sum-of-products mapping of a function (NAND-based implementation) leads to potentially less gate-leakage than a product-of-sums mapping (NOR-based implementation) assuming equal-sized transistors are used, and signal probabilities are not known.

Last updated 1/7/25 CMOS NAND and NOR gates are preferred over AND and OR gates Faster Smaller Less Power

For the designing of efficient circuits with better results, power dissipation has to be reduced without compromising the reliability of the system. This paper includes the various power reduction techniques which are implemented on NAND gate. A comparison between these techniques is proposed.

2019年12月20日 · NAND gate using various techniques such as GALEOR, Power gating, Drain gating, and DFPH is designed and analysed in this paper using DSCH and MICROWIND software at the 45 nm technology.

It is shown that the overall leakage in a NAND -gate is smaller than in a NOR gate if equal size transistors are used. It also compares the leakage value of proposed leakage reduction techniques with conventional NAND gate. Simulation results shows up to 88% in average gate leakage reduction with modified techniques.

This paper presents a glitch-free NAND-based DCDL which overcame this limitation by opening the employ of NAND-based DCDLs in a wide range of applications. The proposed NAND-based DCDL maintains the same resolution and minimum delay of …

2016年1月23日 · Quine-McCluskey method offers better results but is longer and iterative, but scalable. K-Map is a graphical method which is quite simple but gets tedious as the number of inputs increase. But in all cases, they are better than plain guessing, the latter having a …
