Cadence Orcad 157 =link=

Cadence OrCAD 15.7 is a legacy suite of Electronic Design Automation (EDA) tools designed for schematic capture, circuit simulation, and printed circuit board (PCB) layout. Following Cadence's acquisition of OrCAD in 1999, version 15.7 represented a mature stage of the "Unison" suite, which sought to provide a seamless flow from initial design to manufacturing.
