download The OrCAD PCB Designer suite is targeted to address personal productivity needs and those of small design teams.OrCAD PCB Designer with PSpice is scaleable to the Allegro platform (Allegro 200 Series or Allegro 600 Series). Key Technologies within the OrCAD PCB Designer with PSpice Suite: OrCAD Capture, the world.s leading schematic entry solution. Intuitive, easy to use, with sophisticated part search mechanisms, this is the tool of choice for rapid design capture. OrCAD PCB Editor, a constraint driven PCB layout editing tool derived from the Cadence Allegro PCB editor. Its extensive feature set addresses a wide range of today.s design challenges and manufacturability conce s. SPECCTRA for OrCAD , the industry leading solution for automatic and interactive interconnect routing. It includes a route editor and autorouter designed to speed routing task to completion . increasing productivity and shortening over all design cycle times. PSpice AD (included in OrCAD PCB Designer with PSpice) PSpice . AD simulator has the world.s largest installed base of any PCB simulation product and is the most widely used tool for simulating analog and mixed signal designs of any size. This sophisticated, native mixed signal simulator performs functional simulations of digital parts and allows engineers to perform a broad range of PSpice analyses, and contains analog and digital parts ranging from IGBTs and pulse width modulators to DACs and ADCs.
