NI Multisim (formerly MultiSIM) is an electronic schematic capture and simulation program which is part of a suite of circuit design programs, [1] along with NI Ultiboard. Multisim is one of the few circuit design programs to employ the original Berkeley SPICE based software simulation. [ 2 ]
It is a successor of the latest stable release of Berkeley SPICE, version 3f.5, which was released in 1993. A small group of maintainers and the user community contribute to the ngspice project by providing new features, enhancements and bug fixes. Ngspice is based on three open-source free-software packages: Spice3f5, Xspice and Cider1b1:
NI Ultiboard, formerly ULTIboard, is an electronic printed circuit board (PCB) layout program which is part of a suite of circuit design programs, along with NI Multisim. One of its major features is the real time design rule check , a feature that was only offered on expensive work stations in the days when it was introduced.

The final validity test for the example is to simulate the Chebyshev filter frequency response through the full useful range, which will be taken to be 100 MHz to 5 GHz for this case. This range should permit viewing of the equi-ripple |S12| of the pass band between 0 and -1 dB, somewhat steep stop band |S12| falling off at 1GHz, and an equi ...
The first Windows version was released in 1993 as TINA 4.0 for analog, digital, and mixed circuits. [3] TINA 9.0 also includes microcontroller (MCU) simulation, RF network analysis, optimization, and printed circuit board design. [2] TINA development was at version 10, released in 2013, and is at major version 11 since 2016. [4]

In August 1981, the analog equivalent of the first program, Circuit Designer and Simulator, was released. Its integrated text editor created circuit descriptions for a simple, linear, analog simulator. September 1982 saw the release of the first Micro-Cap package as a successor to the Circuit Designer and Simulator. 1982 Micro-Cap; 1984 Micro-Cap 2
