For mixed signal circuit simulation ngspice allows users to create a user-defined node definition file (UDN) of a new device model interface. 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:
MKL and other programs generated by the Intel C++ Compiler and the Intel DPC++ Compiler improve performance with a technique called function multi-versioning: a function is compiled or written for many of the x86 instruction set extensions, and at run-time a "master function" uses the CPUID instruction to select a version most appropriate for ...
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:
Hermes Project: C++/Python library for rapid prototyping of space- and space-time adaptive hp-FEM solvers. IML++ is a C++ library for solving linear systems of equations, capable of dealing with dense, sparse, and distributed matrices. IT++ is a C++ library for linear algebra (matrices and vectors), signal processing and communications ...
Models are described in concise, human-readable algebraic statements. GAMS is among the most popular input formats for the NEOS Server. [citation needed] Although initially designed for applications related to economics and management science, it has a community of users from various backgrounds of engineering and science.
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 ...
The library functions declared by conio.h vary somewhat from compiler to compiler. As originally implemented in Lattice C, the various functions mapped directly to few of the first DOS INT 21H functions. The library supplied with Borland's Turbo C did not use the DOS API but instead accessed video RAM directly for output and used BIOS interrupt ...
The typical cost function during technology-independent optimizations is total literal count of the factored representation of the logic function (which correlates quite well with circuit area). Finally, technology-dependent optimization transforms the technology-independent circuit into a network of gates in a given technology.
