OrCad Layout Plus PCB Tutorial. This is a simple tutorial of OrCAD PCB using a two-layer PCB with through-hole components. The design is a RS232 interface board that contains a DSUB-9 pin connector, 7805 regulator, and a MAX-232 interface chip (16-pin dual-in-line package). The zip archive contains both Capture and Layout Plus files. Part One Layout basics 4 OrCAD Layout User’s Guide Board routing With Layout, you can route your board manually, or you can use Layout’s interactive and automatic routing tools (available in Layout Plus and Layout only). Using manual routing, you guide the routing process and manually route each track.

- OrCAD PCB Editor is tightly integrated with OrCAD Capture. As a result, you can use cross probing to verify information flow between the schematic and the board design, and vice versa. Cross probing lets you select an object in the OrCAD Capture schematic and see the corresponding object in PCB Editor.
- OrCAD is the main software that is used by electronic design engineers and technicians to create electronic design automation. The schematics have to be created and printed for manufacturing the PCB boards. OrCAD PSPICE free download can be used to design the circuits with the tools that are available in the software. This OrCAD viewer freeware is free.
