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.
The Gamma 3 was an early electronic vacuum-tube computer.It was designed by Compagnie des Machines Bull in Paris, France and released in 1952.. Originally designed as an electronic accelerator for electromechanical tabulating machines, similar to the IBM 604, it was gradually enhanced with new features and evolved into a first-generation stored program computer (Gamma AET, 1955, then ET, 1957).
Signal flow graph of a circuit containing a two port. The forward path from input to output is shown in a different color. The dotted line rectangle encloses the portion of the SFG that constitutes the two-port. The figure to the right depicts a circuit that contains a y-parameter two-port network. V in is the input of the circuit and V 2 is ...
The Master Library Module shown removed from its socket in the back of the calculator. Magnetic card storage folio also shown. The TI-59 and TI-58 were the first hand-held calculators to utilize removable ROM program modules. The Master Library Module ROM was included with the TI-59 and TI-58, and contains several useful pre-programmed routines ...
The Victor 3900 is the first electronic calculator to have been built entirely of integrated circuits (ICs). [1] [2] For its era, the 3900 is extremely advanced; it has a 4-inch (100 mm) cathode ray tube screen to produce a 5-line display, has separate memory for storing three intermediate results, supports numerical rounding, and is still "smaller than a typewriter".
Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit (then proclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries. Using four AA-size cells the LE-120A measures 4.9 by 2.8 by 0.9 inches ...

Electronic design automation (EDA), also referred to as electronic computer-aided design (ECAD), [1] is a category of software tools for designing electronic systems such as integrated circuits and printed circuit boards. The tools work together in a design flow that chip designers use to design and analyze entire semiconductor chips.
