Learn how to create and simulate a schematic in Capture CIS Lite.

So you'll want to add PCB footprints to each electronic circuit component in the Properties fields in Capture CIS Lite. After which, open OrCAD PCB Editor Lite and set up all the parameters and constraint rules for your printed circuit board.

Sometimes you will need to create your own schematic symbol for a part. After watching this video you will be able to create your own resistor using OrCAD Capture Part Editor.

In order to create a part, you need to choose or create a library to contain that part. Then put in your general part information, add pins, draw lines, add properties, then save the part.

Just an overview for the phases in this section:

• Phase 1 - Design (already done and chosen for you)

• Phase 2 - Create Parts (already made by Cadence in the libraries)

• Phase 3 - Schematic (you build this from the parts to represent the design from phase 1

• Phase 4 - Simulation (you test your design to see if it works)

In this video, I introduce the project you'll be working on.

Learn how to name the nets in your schematic so you can:

• make it easier to read simulation results

• easier to route your PCB using nets

Verify the functionality of your circuit using PSpice.

In this video you will learn the importance of how often you measure a signal in your circuit. You also get to see the output voltage of your circuit.

You don't have to build every schematic from scratch. You can use pre-made schematics very quickly and I will show you how, so you can use it to transfer to a PCB. You want to keep your simulation circuit and your PCB circuit separate, in case you need to go back to change circuit functionality for simulation.

Add a connector and re-wire the schematic to prepare your schematic for a design rules check (DRC).

Here is a quick tool that gives you an automated way to see if your schematic has electrical errors. After watching this video, you will know how to use Design Rules Check (DRC) to double-check your schematic adheres to electrical rules.

In this video, I explain what is a through-hole Padstack. Find more information at this blog post: http://www.pcb-3d.com/tutorials/how-to-calculate-pth-hole-and-pad-diameter-sizes-according-to-ipc-7251-ipc-2222-and-ipc-2221-standards/

Also, I want to introduce you to the governing document: https://shop.ipc.org/IPC-7351B-English-D

and the organization that governs footprints and padstacks standards, called IPC. You can learn more from their website: http://www.ipc.org

Pad Stack Editor is located in C:\Cadence\SPB_17.2\tools\bin

$168 document - IPC Standard IPC-7351B (established 2010) Every workplace that has a hardware engineer should have this standard readily available. If nobody can find this at your work, that's not good. If you are a freelance/independent contractor or engineer, I highly recommend getting a copy. However, this standard is not needed for this course or to make a footprint that works.

Pad Stack Editor is the secret weapon that you can use to generate all kinds of pad stacks, mounting holes, plated and non-plated holes, slotted holes and solder mask. All footprints start with Pad Stack Editor. After this video, you will know how to use Pad Stack Editor to create an IPC-7251 compliant through-hole pad stack like a pro.

Use this Excel workbook (made into a PDF) to create your footprints and padstacks using the measurements shown in the file. I'm still going to show you how we get the numbers in the spreadsheet though.

The schematic is the conceptual design, but we need to get a physical design as our end goal. For the physical design, we need to know how the parts are represented in 3 dimensions. We need their footprints or land patterns. In this video, you'll see how to make PCB locate your footprints and padstacks for your components.

Download the footprint list. You will build all these footprints from scratch in the next module.

Now that the software knows where to find your custom footprints, just add those footprints to any parts you want to sync them up. This method is not the optimal way to match footprints to parts, but it is the most flexible for on-the-fly design.

Let's define the constraints for your printed circuit board before transferring the concept to physical design. Typically you will have constraints for your PCB first before you ever start designing the circuit. This is the life of a hardware design engineer.

Transfer your idea from just a plan (schematic) to a product (PCB). After watching this video, you will be able to transfer your schematic from being just an idea to starting to become a physical circuit.

No matter what PCB you're working with, generating Artwork film layers manually is time-consuming, and there are better ways to do it across PCBs. After watching this video, you will know how to set up colour views to make the Gerber generation easier and faster.

In Allegro, go to menu - Manufacture - Artwork,

In PCB Designer, go to menu - Export - Gerber
