PCB Design Blogs

With thousands of components connected across a multi-layered board, anticipating the complexity of your layout design at the logic design stage can be quite a challenge. For example, how to ensure that the logical design you are trying to create fun...

The HotFix SPB17.40.028 of 17.4-2019 of Allegro® PCB Editor has been rolled out and is now available for download . This release includes various enhancements, new features, and product changes that address design challenges and speed up the ...

The HotFix 028 (QIR4, indicated as 2022 in the application splash screens) update for OrCAD® and Allegro® is now available at Cadence Downloads . This blog post contains important links for accessing this update and introduces some of the main...

To manufacture a product that performs as you intended, it is imperative that you share accurate stackup definitions with the board fabricator or manufacturer. An accurate stackup definition is critical to getting the best possible performance from ...

Wouldn’t it be convenient if you could customize how to view and access your PCB design environment? You might want to lock the toolbars to prevent the accidental movement of objects or set up design libraries when creating designs. Personalizing the...

Often you want to see the effect of changing multiple parameters on the performance of your design.  For example, you might want to know how the gain or bandwidth of a design is affected when you vary multiple components across a range of values...

Often, you install the Cadence products with default settings and that suffices to work with the tools. However, you might encounter instances when the default settings may not be enough to serve your requirements. For example, when multiple use...

A product is only as good as its components, which makes selecting good components vital. So how does one select the right component? And let’s think about what 'right' means. You have to consider the availability and lead time, the pri...

Today we take a break from our regular posts on Allegro System Capture features and basics to announce a Cadence Training webinar on System-Level Design with Senior Application Engineer, Dave Palumbo. What Is this Webinar About? In the produ...

With boards becoming more complex and lightweight at the same time, designing and manufacturing a cost-effective and reliable PCB has assumed greater significance than ever before. Inaccurate or incomplete design details can affect the fabrication of...

Any circuit you design uses parts that will vary depending on many factors that are not under your control. All components, such as resistors or capacitors, that you use have a tolerance. A 50Ω resistor with a precision of ± 1%, can vary between 4...

Constraint capture made easy with in-context editing right next to the circuitry being constrained. Read on to find the power of the Docked Constraint Manager in Allegro System Capture

“We must accept finite disappointment, but never lose infinite hope.” – Martin Luther King, Jr. By 2021, the changed working environment, transformed digitally in ways we never expected, taught us important life lessons. Despite the...

In multilayer PCB designs, copper areas have many uses and are critical to the performance of a design. As a designer, you have a fair idea of how and when to pour in copper. However, copper areas are created in the form of shapes and any change in the design, for example, moving components or adjusting routing, affe...

If you are interested in the performance of a circuit that can be best described by a waveform instead of a value, say a practical filter circuit response, curve-fitting is the choice. You can use an external specification composed of measurement data defined in an external data file ...

Components, or parts, are the basic building blocks of a PCB design. It is of utmost importance that the components present in the design, their graphics, electrical, and part definitions, match the latest and updated li...

Your products must perform well in terms of their requirements. For a product to perform well, you must ensure the design parameters are tuned for the best performance possible. For example, you might need the output voltage to hover around 20V or th...

While designing a layout within Allegro® PCB Editor, designers zoom in and out or pan in the design canvas to take a closer look at a component’s placement and connectivity. Because they frequently zoom or pan when creating or edi...

In the world of PCB design, shorter delivery deadlines have less scope of re-spin cycles. Before manufacturing the board, every designer wants to see what the manufactured board would look like. Allegro 3D Canvas , enabled within Allegro® PCB Edi...

Sharing design intent and stackup information with your manufacturer at the beginning of the design process avoids manufacturing and assembly issues that may impact the product design, and eventually, delay the product delivery. However, without havi...

Component placement is one of the most critical aspects of PCB designing. As the number of components and layers increases, the complexities of placing components increase manifold. Allegro PCB Editor, with its streamlined and efficient component placement...

Tight deadlines, multiple people working on a design, inevitable errors…there are so many things that can affect the design and development of a PCB. Ensuring a smooth flow of work is easy enough if you are just one designer or a small team. A...

We all want to be sure, or as sure as we can be, that our products will work as expected in the real world under circumstances that may not always be under our control or per our specifications. We want to be adequately aware of how the output of the...
