  1. Orcad 9.2 Embedded System Project

  2. Orcad Capture • Capture is an electronic design environment • Capture is used to draw a schematic design of your electronic device • Logical connections • Part symbols • Starting Orcad Capture (in Windows) • Start – Programs – Cadence PSD – Capture

  3. Orcad Layout • Layout is a circuit board layout tool • Layout is used to design the physical printed circuit board (PCB) of your electronic device • A netlist (.MNL file) produced by the Capture tool is used as an input to the Layout tool

  4. Orcad Layout (cont’d) • Starting Orcad Layout (in Windows) • Start – Programs – Cadence PSD – Layout

  5. PCB Design Process • Create a new project with Orcad Capture • Draw the schematic design of you device • Part symbols • Logical connections between parts • Create the netlist (.MNL file) from your schematic design

  6. PCB Design Process (cont’d) • Start Orcad layout • Load a technology template file (.TPL or .TCH file) • Load the netlist (.NML) file created with Orcad Capture

  7. PCB Design Process (cont’d) • Design the PCB of your device • Draw the outline of your PCB • Place physical components (footprints) • Draw physical (copper) connections between components • Finally, post process your PCB design which will produce files (.TOP, .BOT, .TAP) for the PCB milling machine (located in SÄ125).

  8. PCB Design Process (cont’d) • Send the three files (.TOP, .BOT, .TAP) to Kirsi Kullaa (kirsi.kullaa@ee.oulu.fi) for manufacturing of your PCB
