  2. Ngspice - Wikipedia

    en.wikipedia.org/wiki/Ngspice

    The implementation of the node is created and simulated by using C language with macros which is compiled by standard C/C++ compilers. New models can be added to the simulator using: Behavioral modeling: Internal B-, E-, and G-sources, as well as R, C and L devices, offer modeling by mathematical expressions, driven by node voltages, branch ...

  3. C-element - Wikipedia

    en.wikipedia.org/wiki/C-element

    Since the majority gate is a particular case of threshold gate, any of known realizations of threshold gate [64] can in principle be used for building a C-element. In the multiple-valued case, however, connecting the output of majority gate to one or several inputs may have no desirable effect.

  4. Tseytin transformation - Wikipedia

    en.wikipedia.org/wiki/Tseytin_transformation

    An OR gate with two inputs A and B and one output C satisfies the following conditions: if the output C is true, then at least one of its inputs A or B is true, if the output C is false, then both its inputs A and B are false. We can express these two conditions as the conjunction of two implications:

  5. Nonlinear programming - Wikipedia

    en.wikipedia.org/wiki/Nonlinear_programming

    If the objective function is quadratic and the constraints are linear, quadratic programming techniques are used. If the objective function is a ratio of a concave and a convex function (in the maximization case) and the constraints are convex, then the problem can be transformed to a convex optimization problem using fractional programming ...

  6. Fredkin gate - Wikipedia

    en.wikipedia.org/wiki/Fredkin_gate

    The basic Fredkin gate [3] is a controlled swap gate (CSWAP gate) that maps three inputs (C, I 1, I 2) onto three outputs (C, O 1, O 2). The C input is mapped directly to the C output. If C = 0, no swap is performed; I 1 maps to O 1, and I 2 maps to O 2. Otherwise, the two outputs are swapped so that I 1 maps to O 2, and I 2 maps to O 1. It is ...

  7. Boolean circuit - Wikipedia

    en.wikipedia.org/wiki/Boolean_circuit

    The ∧ nodes are AND gates, the ∨ nodes are OR gates, and the ¬ nodes are NOT gates. In computational complexity theory and circuit complexity, a Boolean circuit is a mathematical model for combinational digital logic circuits. A formal language can be decided by a family of Boolean circuits, one circuit for each possible input length.

  8. Compiler Description Language - Wikipedia

    en.wikipedia.org/wiki/Compiler_Description_Language

    The CDL2 compiler is able to flag the possible violations thanks to the requirement that the direction of parameters (input, output, input-output) and the type of rules (can fail: test, predicate; cannot fail: function, action; can have a side effect: predicate, action; cannot have a side effect: test, function) must be specified by the programmer.

  9. process.h - Wikipedia

    en.wikipedia.org/wiki/Process.h

    process.h is the C header file which contains function declarations and macros used in working with threads and processes. Most C compilers that target DOS, Windows 3.1x, Win32, OS/2, Novell NetWare or DOS extenders supply this header and the library functions in their C library.
