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. ULTIboard was originally created by a company named Ultimate Technology, which is now a subsidiary of National Instruments. Ultiboard includes a 3D PCB viewing mode, integrated import and export features to the schematic capture, and simulation software in the suite, Multisim.
