The compiling the project isn't strictly needed if you just tweak the schematic. And if you've been adding and removing components, check the component links to make sure all pcb components are linked to schematic components.

Are you catching them all in your current design criteria review process? Read on to find out how you can better catch errors as a project manager or team lead.

Over 10 years later, our designs have become more complex than ever. And when it comes to designing complicated circuits, with multiple high-pin count devices and large on and off-board connectors, there comes a considerable risk for errors to escape into the manufacturing process. I recently sat down with Altium to talk about the new technology we are working on at Valydate for Schematic Integrity Analysis checks.

Compiling and Verifying the Design

Valydate has an interesting history. The solution? Start with a smaller investment, develop our technology through a service-based offering and show off our technology through the evaluation of real client projects. Did it work? Big time. Report after report came back from our client projects on similar errors that designers kept making in their schematic review process, some of which you might find that you are making yourself.

Valydate spent two years, from to running schematic verification reports for hundreds of schematics. We split up our findings into two categories:. We were surprised about the kind of critical, design-breaking errors we were finding in our schematic review checks. Have you ever made these mistakes in your design process?

Defects also provided some interesting insights, with the range of potential defects being far greater than critical errors. The most of them all? Do any of these look familiar to you? What I found most fascinating as we neared the completion of our 2-year study is the commonality between the design errors. There were hundreds of different schematics in this study, and all of them had the same design-breaking flaws. When it comes to meeting a release window, errors are going to slip through the cracks.

How do you ever know what caused a design flaw to slip through to manufacturing? At the end of the day, I think it really comes down to how much time you are willing to invest in your schematic review process. While the human-review process worked great a decade ago, we are now at a place where schematics are just too complicated to reliably verify by hand. What we really need to see is a Schematic Integrity Analysis tool that can run all of these checks for you, and free up your time for more pressing matters.

Stay tuned, Altium users, there are good things ahead.Parent category: Violations Associated with Documents. Default report mode:.

Created using Figma.This integrates with the schematic and PCB comparison features, making it easy to quickly compare and identify differences between two revisions of a schematic or PCB document, and for PCB designs, resolving concurrent revision conflicts using Altium Designer's Collaboration capabilities. There are a few preliminarily steps that need to be completed before using Version Control for design projects.

In essence, these are:. The panels are populated with project documents and their related VCS status when opened in Altium Designer. The Projects panel displays all projects that are currently open in Altium Designer, along with their constituent documents and the associated Version Control status for each file. The VCS file status in the panel is indicated through a series of icons that relate to specific file conditions detected by the version control system.

The condition status for each file is, in general terms, relative to its equivalent that exists under version control in the linked repository. The VCS commands in the Projects panel are accessed from the Version Control option in the panel's right click context menu. A restart may be required to affect the change. The VCS file status in the panel is indicated through a series of descriptions and matching icons that relate to specific file conditions detected by the version control system.

To perform a VCS action on a specific file, right click on its entry in the panel and select the desired command — for example, Commit, Update, Resolve conflict etc.

The Storage Manager panel also includes detailed VCS and history events as time-stamped streams in the lower sections of the panel. For both the Projects and Storage Manager panels, the current VCS status of each file that is under version control is displayed along with its entry in the panel. The version control system essentially monitors and compares the files in the working folder to their counterparts in the design repository.

Altium Designer both requests and exchanges information with the version control system via its VCS interface, and responds to the comparative file status conditions accordingly.

In practice, this manifests itself in the Projects and Storage Manager panel file icons, through a range of VCS alerts, and by appropriate changes in the available file management commands. The file in the local working repository is newer than its counterpart in the remote Git repository. This occurs when a local file has been modified, saved and committed to the local repository, but not yet Pushed to the remote repository. Project files can be added to a version control repository using the commands from either the Projects or Storage Manager panels, which involves the steps of registering the files for addition and then committing those files to VCS.

The process shown below uses the Projects panel, which more conveniently at hand, but it is worth noting that the Storage Manager panel provides more VCS detail and options. The most direct approach to adding a project and its constituent documents to version control is to add the complete project folder to the VCS repository. The following Add to Version Control dialog provides options to select the target design repository and subfolder.

The dialog will then populate with files entries derived from the source folder, with the project's constituent files selected — if necessary use the checkboxes enable or disable files for inclusion.Explore the latest content from blog posts to social media and technical white papers gathered together for your convenience.

Contents Design Verification Strategies Verification - are we building the product right? What do designers use as part of their daily arsenal in their approaches to design verification in order to be confident that their design is ready for PCB layout? Verifying that a design is correct is often the most difficult and yet also the most important aspect during this phase.

The focus of this article will be on a discussion of issues that typically cause problems for designers before the PCB layout phase, reveal strategies that can be used by the designer to avoid these pitfalls, and how Altium Designer can be leveraged to work for them. A good strategy for design checking and debugging integrates test case design techniques into a set of well-planned series of steps that result in the successful completion of designs and delivery to market.

What you need is a roadmap for everything that will be conducted as a part of this process. The best way to approach verifying your design is to have software that gives you as much help as possible! Testing is often a much broader topic that is also referred to as verification and validation.

Verification refers to those activities and procedures that ensure that a design is being correctly implemented. Validation refers to a slightly different set of activities that ensure a design is traceable to a certain set of requirements. It's an important difference to distinguish. More easily said:.

Verification - "Are we building the product right? As mentioned before, the scope of this article will focus on verification activities specific to electronic design in the pre-PCB layout phase, when problems are often the most difficult to find and require real diligence on the part of the designer. These approaches will be what we call strategies, and will focus on the more practical, hand's-on techniques that a designer can use as part of his daily arsenal for ensuring that they consistently hit their expected delivery dates with the desired level of quality - and successfully get the product right!

Using Version Control

Designs are developed and engineered, not stamped out in the manufacturing sense. Because of this, there are many technical elements that come into play during the verification process, and it's worth mentioning that often the human element underlies most of them and can greatly influence the end result and quality.

When a design is created and built, the human creative process becomes transformed into a physical form! For example, in companies that deliver mission-critical applications such as the space industry, often a major hurdle that must be overcome is the psychological effect on the quality of the review. No engineer is a robot and many details can influence the quality. Time-to-market stress is another major element that can create bad designs and nearly every company, regardless of their product and application, is faced with it.

While the focus of this article will not be on the human element, it's important to understand that this is an inherent factor that governs and affects the rest of the process. So what are some of the more proven procedures used by the majority of successful companies who have adopted a more diligent approach to verification, and can be used in nearly every sense?

Let's take a look:. Reviews that are conducted will usually include a generated schematic part list and verification that all of the part types are the correct ones, at the very minimum. Lastly, that all appropriate changes are properly updated to the PCB, especially in cases where there may be PCB rules embedded line width, clearanceor test points in the schematic.

Almost all companies have a database and use their own specific part numbers. One of the biggest challenges that designers face before they even start designing is verifying their libraries, and that approved symbols and footprints have been used. Of course, this begins with creating or accessing the actual library symbols and footprints since you can't start anything else if there are no parts previously available.

An integrated library in Altium Designer is one where the source symbol, footprint, and all other information e. SPICE and other model files are compiled into a single file. Using integrated libraries are a great way to start as they save tremendous time when verifying datasheets and footprints in a library.

The advantage if the integrated library which not all CAD packages have is that you do it at the beginning and only once. You can then trust the Altium Designer won't make modifications in your work and displays everything that the designer needs to see when they need to see it.Explore the latest content from blog posts to social media and technical white papers gathered together for your convenience.

Parent page: Workspace Manager Panels. Click on an entry in the Compile Errors panel to go to the document source. The Compile Errors panel is used to display detailed information about the offending object s associated with a Compiler-specific message being cross-probed from the Messages panel. You can use the panel to jump to the object s in the source document s.

To open the Compile Errors panel, click the Design Compiler button at the bottom-right of Altium Designer and select the Compile Errors entry from the pop-up menu. Note that panels can be configured to be floating in the editor space or docked to sides of the screen. The Compile Errors panel will appear automatically when cross probing from a Compiler-specific message in the Messages panel that is associated to a schematic source document. The panel lists the message and the offending design object s that are causing the problem.

If the associated schematic document is open or open and hiddenclicking on an object entry in the panel will cross-probe to the object on the document.

Sounds exciting! Did you know we offer special discounted student licenses?Design Rule Checking DRC is a powerful automated feature that checks both the logical and physical integrity of a design. This feature should be used on every routed board to confirm that minimum clearance rules have been maintained and that there are no other design violations. It is particularly recommended that a batch mode design rule check always be performed prior to generating final artwork.

Click on this top-level folder to list all checkable rule types on the right side of the dialog. Alternatively, click on a specific category to list only those design rule types associated to that category. For a rule to be subject to the Online DRC, the following three requirements must be met:.

Ensure that design rules you wish to have monitored by the Online DRC are actually enabled for use in the design. Ensure that the rule type is enabled for Online DRC. Ensure that the Online DRC feature is enabled. Whereas Online DRC only detects new violations - violations that are created after the feature is enabled - Batch DRC allows a check to be manually run at any time during the board design process.

Various additional options are available when running a Batch DRC, including the ability to generate a report file. Two key options highlighted in the following image are:.

After the check has completed, all violations are listed as messages in the Messages panel. Rules that are not present in the design are not tested. Options available on the PCB Editor - Reports page of the Preferences dialog allow specification of report format, and whether the report is automatically displayed after generation.

Each violation that was located is listed with full details of any reference information, such as the layer, net name, component designator, and pad number, as well as the location of the object. Checking the design against specified design rules is one thing, but what happens when one or more of those rule are violated? The PCB Editor includes powerful violation display options to indicate where violations exist in a clear, visual way.

These graphics provide a visually cleaner DRC landscape.

Length Matching in Altium

When a particular design rule is violated, the associated custom violation graphics where applicable are only drawn on the layer s involved with that violation. In some cases, the graphic shows not only where the violation is occurring, but also why - displaying the constraint value defined for the rule and indicating how the offending primitive s are either below or above this value.

Example illustrating the custom graphics used for width and minimum annular ring rule violations. Additional examples of custom violation graphics.

In addition to the custom violation graphics, a violations 'overlay' is available for setup and use. The overlay draws over design primitives.

Use a violation overlay as an alternative to the custom violation graphics when displaying DRC violations. Using a combination of the two violation display types can prove useful in terms of providing a 'coarse' and 'fine' indication of violations. When zoomed out, the violation overlay can flag where a violation exists, then zoom in to view the detail delivered by the associated custom violation graphic.

To give further flexibility when displaying rule violations in the workspace, the two violation display types - violation details custom violation graphics and violation overlay - have separate associated system colors.

This allows you to differentiate between the two using different, distinct colors. However, there may be a sizable quantity of violations flagged, and now the task becomes one of resolving those violations.

The secret to keeping the process manageable is to develop a strategy. One strategy is to limit the number of violations that are reported.

When setting up the report options in the Design Rule Checker dialogset the Stop When Found feature to a small number. Another strategy is to run the DRC in a number of stages.
