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.
[2] In Arena, the user builds an experiment model by placing modules (boxes of different shapes) that represent processes or logic. Connector lines are used to join these modules together and to specify the flow of entities. While modules have specific actions relative to entities, flow, and timing, the precise representation of each module and ...
In 2003, ModelSim 5.8 was the first simulator to begin supporting features of the Accellera SystemVerilog 3.0 standard. [1] In 2005 Mentor introduced Questa to provide high performance Verilog and SystemVerilog simulation and expand Verification capabilities to more advanced methodologies such as Assertion Based Verification and Functional ...
Due to the free form style of the Editor and the CAD based interface the creation of different types of roller coasters is not limited by the style of track chosen for the simulation, and as such Wooden roller coasters can have the same elements as a Steel roller coaster, whilst not being "true to life". Below is a list of the track types (with ...
However, until the late 1970s, most minicomputers did not have a multiply instruction, and so programmers used a "multiply routine" [1] [2] [3] which repeatedly shifts and accumulates partial results, often written using loop unwinding. Mainframe computers had multiply instructions, but they did the same sorts of shifts and adds as a "multiply ...
For 8-bit integers the table of quarter squares will have 2 9 −1=511 entries (one entry for the full range 0..510 of possible sums, the differences using only the first 256 entries in range 0..255) or 2 9 −1=511 entries (using for negative differences the technique of 2-complements and 9-bit masking, which avoids testing the sign of ...

ModelSim is a multi-language environment by Siemens [1] (previously developed by Mentor Graphics, [2]) for simulation of hardware description languages such as VHDL, Verilog and SystemC, and includes a built-in C debugger. [3] [2] ModelSim can be used independently, or in conjunction with Intel Quartus Prime, PSIM, [4] Xilinx ISE or Xilinx ...
