Select to number everything sequentially. Click OK . 2. Running a Design Rules Check (DRC)
You can leave designators as ? for now, as we will auto-number them in the next step. Section 3: Preparing the Schematic for PCB Layout
OrCAD organizes components in library files ( .olb extension). To place components:
Before moving to layout, ensure all components have matching physical footprints. orcad 16.6 tutorial
Select the standard GND or VCC symbols from the CAPSYM library.
A: Yes, but it may require enabling Windows 7 Compatibility Mode for the installation folder shortcuts. Some users also report needing to disable high-resolution display scaling to make the icons readable.
Differential pairs (e.g., for USB, HDMI, Ethernet) require matched lengths and controlled impedance. Select to number everything sequentially
Define the film layers you need to export. A standard 2-layer board requires: Top and Bottom Etch (Copper) Top and Bottom Solder Mask Top and Bottom Silkscreen (Text ink) Board Outline Click to export the .art files. 2. Generating NC Drill Files
You will notice your parts have generic names like R1 , R2 , C1 , and values like 1k or 10u . You must edit these to match your circuit requirements.
In the Options panel, set the class to and choose your layer (e.g., Bottom ). Running a Design Rules Check (DRC) You can

OrCAD 16.6 is a suite of tools designed for the electronic design automation (EDA) process. Its primary strengths lie in its stability, extensive component library integration, and seamless transition from schematic to PCB layout.
The fine lines connecting your placed parts are called "ratsnest" lines. They guide your manual traces. Go to (Hotkey: F3 ).
