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 ]
NI Ultiboard or formerly ULTIboard is an electronic Printed Circuit Board 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.
OrCAD Systems Corporation was a software company that made OrCAD, a proprietary software tool suite used primarily for electronic design automation (EDA). The software is used mainly by electronic design engineers and electronic technicians to create electronic schematics, and perform mixed-signal simulation and electronic prints for manufacturing printed circuit boards (PCBs).
Process variations occur when the design is fabricated and circuit simulators often do not take these variations into account. These variations can be small, but taken together, they can change the output of a chip significantly. Temperature variation can also be modeled to simulate the circuit's performance through temperature ranges. [8]

The National Instruments Electronics Workbench Group [23] is responsible for creating the electronic circuit design software NI Multisim and NI Ultiboard, [24] which was previously a Canada-based company that first produced MultiSIM, and integrated ULTIboard with it.
A CBS News investigation found dozens of law enforcement leaders — sheriffs, captains, lieutenants, chiefs of police — buying and illegally selling firearms, even weapons of war, across 23 U.S ...
The process of circuit design can cover systems ranging from complex electronic systems down to the individual transistors within an integrated circuit. One person can often do the design process without needing a planned or structured design process for simple circuits.
