The world of electronic design automation (EDA) software for integrated circuit (IC) design is dominated by the three vendors Synopsys, Cadence Design Systems and Siemens EDA (Formerly Mentor Graphics, acquired in 2017 by Siemens) which have a revenue respectively of 4,2 billion US$, 3 billion US$ and 1,3 billion US$.
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Static timing analysis: analysis of the timing of a circuit in an input-independent manner, hence finding a worst case over all possible inputs. Layout extraction: starting with a proposed layout, compute the (approximate) electrical characteristics of every wire and device. Often used in conjunction with static timing analysis above to ...
CircuitMaker is electronic design automation software for printed circuit board designs, for the hobby, hacker, and maker community. [1] [2] CircuitMaker is available as freeware, and the hardware designed with it may be used for commercial and non-commercial purposes without limitations. [3]
Simulation software allows for the modeling of circuit operation and is an invaluable analysis tool. Due to its highly accurate modeling capability, many colleges and universities use this type of software for the teaching of electronics technician and electronics engineering programs.
An operational amplifier is an amplifier circuit which typically has very high open loop gain and differential inputs. Op amps have become very widely used as standardized "gain blocks" in circuits due to their versatility; their gain, bandwidth and other characteristics can be controlled by feedback through an external circuit. Though the term ...
An example of a Gainclone The very first Gainclone amp built by R. Salamat / Triodont (AudioAsylum) ca.1999. Gainclone or chipamp is a type of audio amplifier made by do-it-yourselfers, or individuals interested in DIY audio. It is a design based on high-power integrated circuits, particularly the National Semiconductor Overture series. The ...
The simulator first divides the circuit into analog and digital portions. The analog circuitry is simulated with the time-step driven SPICE engine, while the digital parts are simulated separately with an event-driven simulation engine. The CircuitLogix digital engine was developed directly in .NET, faster than SPICE macros. Because the ...
