LTspice is a SPICE-based analog electronic circuit simulator computer software, produced by semiconductor manufacturer Analog Devices (originally by Linear Technology). [2] It is the most widely distributed and used SPICE software in the industry. [6]
Other tools allow creating Bézier curves, freehand drawing of lines (pencil), or calligraphic (brush-like) strokes which support a graphics tablet. [16] Inkscape is able to write and edit text with tools available for changing font, spacing, kerning, rotation, flowing along the path or into a shape. Text can be converted to paths for further ...
Logic Friday is a free Windows program that provides a graphical interface to Espresso, as well as to misII, another module in the Berkeley Octtools package. With Logic Friday users can enter a logic function as a truth table, equation, or gate diagram, minimize the function, and then view the results in both of the other two representations.
A logic gate is a device that performs a Boolean function, a logical operation performed on one or more binary inputs that produces a single binary output. Depending on the context, the term may refer to an ideal logic gate, one that has, for instance, zero rise time and unlimited fan-out, or it may refer to a non-ideal physical device [1] (see ...
A majority gate returns true if and only if more than 50% of its inputs are true. For instance, in a full adder , the carry output is found by applying a majority function to the three inputs, although frequently this part of the adder is broken down into several simpler logical gates.
This schematic diagram shows the arrangement of four OR gates within a standard 4071 CMOS integrated circuit. OR gates are basic logic gates, and are available in TTL and CMOS ICs logic families. The standard 4000 series CMOS IC is the 4071, which includes four independent two-input OR gates. The TTL device is the 7432.

The skip-logic consists of a -input AND-gate and one multiplexer. T S K = T A N D ( m ) + T M U X {\displaystyle T_{SK}=T_{AND}(m)+T_{MUX}} As the propagate signals are computed in parallel and are early available, the critical path for the skip logic in a carry-skip adder consists only of the delay imposed by the multiplexer (conditional skip).
