Easy-to-Use AR Technology

Easy-to-Use AR Technology

The inspectAR tool uses off-the-shelf devices with a hybrid of in-house and custom AR technology. Repeat a two-step calibration process for the front and back side of the board to get a project up and working in minutes. No fiducials are required, and any color combination of silkscreen, solder mask, and work surface background will work. Once tracking has been attained, you can zoom in either through software or by moving the camera physically until as little as 20% of the board is in view. If you lose tracking, you only have place 80% of the board back in view to regain tracking and start viewing overlays again.

Any PCB Shape Will Work

From simple rectangles to circular boards, irregular shapes with internal cutouts, and custom profiles made to fit form-factor cases, the inspectAR tool will still work. The custom calibration matches the profile of your board exactly, accounting for overhanging, side-mounted components, and any internal cutouts or slots your design may have. There is no limit on the size of the board that you can use, as everything in the inspectAR tool’s videos is filmed using circuit boards that are 30cm or smaller in their largest dimension. Boards larger than 30cm will work, just initially position your camera far enough back to get 80% of the board in view. Mobile devices make this easy, and you can move the camera forward and zoom in further after that. You also may not need the fine detail of being able to view tiny and fine pitch components on a larger board. You can easily exceed the 30cm dimension limit if you do not need this level of detail. The following is an example of larger components such as header pins and connectors with a two-foot measure for scale of what you can do.

Simple Calibration Process

Simple Calibration Process

The inspectAR tool’s calibration process really is like depositing a check at a bank from your smartphone, albeit a bit more manual since it is dealing with a circuit board and nota check of known dimensions. The PCB must be on a flat surface, and you should make sure that the camera above is also level. From there, you just need to confirm where you see the board outline in the image that the inspectAR tool shows you. The inspectAR tool uses this board outline to calculate the approximate location of your AR overlays and compute the location the board in real-time once you enter the AR window. You can make small adjustments to your overlays after calibration.

AR Probing

You can directly interact with a board in the real world by clicking or tapping on components from within the inspectAR tool. Hover over a component and it will give you its reference designator. Click a component and you can view the design-specific pinout natively from the inspectAR tool. If you flip the board over, all the overlays that you are looking at will be reversed and mirrored to match the design.

Topology-Based Menu System

Topology-Based Menu System

Every overlay in the inspectAR tool understands its topology in relation to others. For example, a component knows which net each pin is connected to and a net knows which components are connected to. Therefore, you can use engineering intuition rather than specific knowledge of a design to navigate around the board. Once you activate a component, you’ll then see which net each pin is connected to. You can keep following the flow of power or move on to different functional and logical nets to explore communications, sensor behavior, etc.

Built-in Work Instruction and Documentation Tool

Engineers spend countless hours preparing in-lab documentation using tools such as Microsoft Paint or PowerPoint. Step one is painstakingly lining up shapes and symbols to match the image you have taken. The inspectAR tool does this automatically and, from its screenshot markup tool, you can add your own custom drawings and instructions to the image. Instructions can then be attached to any net or component and viewed natively alongside the components in the AR Window.

Team-Wide Commenting

Team-Wide Commenting

Comments can be attached to any net or component in order to streamline discussions and solve issues faster. Comments can be tagged and coded according to priority or function.

Share Subsystems with Save States

Save states allows you to group together various nets and components to create an entire subsystem. You can share this directly to a team member in order to give them confidence of the area of the board they need to work on, eliminating confusion caused from looking at the wrong area of the board.

Easy Color Selection

Easy Color Selection

By default, overlays within inspectAR are colored by layer just like you would see in an EDA. You can also color them by net if you like to maximize contrast once you are viewing the board in AR. When viewing similar, nearby signals with color-by-net you can minimize your pin swapping errors and stop yourself from confusing signals with each other when they overlap across different layers of layout.

Desktop Camera Has Video Microscope-Inspired Control

Many inspectAR users are already familiar with putting aboard underneath a microscope in the electronics lab. While a video feed will never truly replace the resolution and zero-latency feedback of an optical microscope, the inspectAR tool gives you as much of that control and precision as possible. A full camera control panel allows you to adjust your focus and zoom completely manually if needed. You can also switch over to automatic control, which will give you an experience more similar to a smartphone camera.

Built-in Component Search

Built-in Component Search

Finding a data sheet to look up component pin mapping before probing is a difficult, problematic task when you must guess which orientation that part was placed on the board by the designer. Finding a particular temperature curve or the expected packets within the datasheet for a given signal can be similarly difficult. The inspectAR tool’s built-in part search leverages Cadence’s Unified Component search to bring datasheets and parametric part information right into the lab. PDFs can be viewed natively from within the inspectAR tool right alongside your overlays and board.

Interactive Part Search

The inspectAR tool allows you to select overlays based on a keyword search of your entire BOM. For example, searching for “10k” can pull up all 10k resistors on your board. Searching the part number of a single 10k resistor will pullup that entire line item from the BOM. You can directly search any net or component from this interface, plus you can combine searches to create custom groups of components.

File Attachments

File Attachments

You can turn your board into a live and interactive piece of documentation by attaching files to nets and components. This way you can share custom data sheets, simulations, and measurements while specific integrations are being developed.
