As integrated circuits become more inexpensive and compact, many new types of products, such as digital cameras, digital camcorders, and digital television [2], are being introduced, based on digital systems.

This is necessary for further functionality and processing capability to be added to the design. Standard cell design is the defacto standard for most IC designs. The other end of the spectrum is full custom design whose efficiency is very high, but with a large design time. In this paper we investigate the use of prototype module generators to improve the energy efficiency of the design over the standard cell design while trading off some design time. We also show the possible research opportunities for filling in the further EDA tools for low power.

Ultralow-power adiabatic circuit semi-custom design Abstract: This brief shows that a conventional semi-custom design-flow based on a positive feedback adiabatic logic PFAL cell library allows any VLSI designer to design and verify complex adiabatic systems e. A family of semi-custom PFAL carry lookahead adders and parallel multipliers were designed in a 0. Post-layout simulations show that semi-custom adiabatic arithmetic units can save energy a factor 17 at 10 MHz and about 7 at MHz, as compared to a logically equivalent static CMOS implementation.

As integrated circuits become more inexpensive and compact, many new types of products, such as digital cameras, digital camcorders, and digital television [2], are being introduced, based on digital systems. Consequently, logic design must be done under many different motivations. Since each case is different, we have different design problems. Logic functions that are frequently used by many designers, such as a full adder, are commercially available as off-the-shelf IC packages. A package means an IC chip or a discrete component encased in a container. Logic networks that realize such logic networks are often called standard logic networks. A single component, such as a resistor and a capacitor, is also commercially available as an off-the-shelf discrete component package.

Semi-custom Layout Design and Simulation of CMOS NAND Gate

Full-custom design is a methodology for designing integrated circuits by specifying the layout of each individual transistor and the interconnections between them. Alternatives to full-custom design include various forms of semi-custom design, such as the repetition of small transistor subcircuits; [1] one such methodology is the use of standard cell libraries standard cell libraries are themselves designed using full-custom design techniques. Full-custom design potentially maximizes the performance of the chip, and minimizes its area, but is extremely labor-intensive to implement. Full-custom design is limited to ICs that are to be fabricated in extremely high volumes, notably certain microprocessors and a small number of ASICs. The mask sets are required in order to transfer the ASIC designs onto the wafer.
