Simplification by Essential Prime Implicants. A row with a single X represents a (relatively) essential vertex, and the corresponding column represents a (relatively) essential prime implicant. The column must be selected in the final cover because any prime cover for the function will have to co...
Simplification on Logic Circuits Extracted from Transistor Circuits for Logic Verification PurposeIncrease in chip complexity has made logic verification tools play a more and more important role in VLSI design. Recently, several logic verification algorithms [2,3,4,5,6] for combinational circuits have...

As examined in Section 2.7.3, truth tables may include don't care's to allow more logic simplification. HDL Example 4.27 shows how to describe a priority circuit with don't cares. Synplify Premier synthesizes a slightly different circuit for this module, shown in Figure 4.23, than it did ...
It starts with a discussion of combinational logic: logic gates, minimization techniques, arithmetic circuits, and modern logic devices such as field programmable logic gates.In this course students will learn about basic definition of digital system, minimization and simplification of the function and ...
E.g., we willlike to address the simplification problem for TP5000: Given anode N with the associated logic function fand a corresponding sum-ofproducts representation (SOP), derive another SOP for f that makes N more balanced. Finally, we wish to push large industrial designs through our ...
Such simplification is reasonable because the layout information is not yet available, and the die size of commercial FPGAs is not open. Figure 11 (a) 6-LUT with carry chain Open in figure viewerPowerPoint Homogeneous LUT structures with carry chain. Figure 11 (b) 4-LUT with carry chain ...
Abstract We present an overview and analysis of existing work in the design of online testable reversible logic circuits, as well as propose new approaches for the design of such circuits. We explain how previously proposed approaches are unnecessarily high in overhead and in many cases do not ...
The invention takes advantage of a Boolean functional simplification of one of two logically equivalent carry functions: Ci=(A♁B) (C1-1)+(A♁B/ ) B (8) Ci=(A♁B) (Ci-1)+(A♁B/ ) A (9) The propagation delay of the circuit provided by the invention is less dependent on...
This simplification is achieved by viewing the two boundary scan cells of FIG. 3 as a single programmable entity, a "double" boundary scan cell. Therefore, an I/O cell for this embodiment comprises one IOD and one double boundary scan cell. In another embodiment, the I/O cell comprises ...
