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.
Added AIS_ViewController mapping user input to 3D viewer camera manipulations. Added support of 3/4 and box clipping configurations to 3D viewer. Added fast HLR-alike OpenGL rendering mode. Removed legacy local context functionality from AIS and legacy Boolean operations. Open CASCADE Technology 7.3 2018-05-29 — —
Logic simulation is the use of simulation software to predict the behavior of digital circuits and hardware description languages. [ 1 ] [ 2 ] Simulation can be performed at varying degrees of physical abstraction , such as at the transistor level , gate level , register-transfer level (RTL), electronic system-level (ESL), or behavioral level.
Following is a list of notable software, computer programs, used to develop a mathematical representation of any three dimensional surface of objects, as 3D computer graphics, also called 3D modeling.
Gate bias is varied in a nanowire MOSFET at drain bias Vd=0.6V. Notice the confined energy levels as they move with gate bias. Physics driven device modeling is intended to be accurate, but it is not fast enough for higher level tools, including circuit simulators such as SPICE. Therefore, circuit simulators normally use more empirical models ...
The process usually begins with the conversion of the specification into a block diagram of the various functions that the circuit must perform, at this stage the contents of each block are not considered, only what each block must do, this is sometimes referred to as a "black box" design. This approach allows the possibly highly complex task ...
AnyLogic supports interactive 2D and 3D animation. [55] AnyLogic allows users to import CAD drawings as DXF files, and then visualize models on top of them. [61] This feature can be used for animating processes inside objects like factories, warehouses, hospitals, etc. This functionality is mostly used in Discrete Event (process-based) models ...
It is possible to create multi-level compound gates, which combine the logic of AND-OR-Invert gates with OR-AND-invert gates. [7] An example is shown below. The parts implementing the same logic have been put in boxes with the same color. compound logic gate for (CD + B) A, plus CMOS version.
