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...

Use AXL-SKILL and customized toolbars and icons to access frequently performed tasks that you have automated. Your own set of menus and icons for ease and speed...

I know it and you know it. Electronic design cycles are a challenge. All that back and forth between designers, board engineers, CAD librarians, mechanical designers, suppliers, manufacturers, and component engineers can be difficult to manage. Typic...

Placing component leads accurately as per the datasheet is an important task while creating a package footprint symbol. As the pin pitch goes down, the size and location of the component lead play a crucial role in the assembly of the components. The...

A guest blog to take your focus away from normal news and feature information that you are accustomed to reading about in the world of PCB Design blogs to let you know about Cadence’s recent ventures into the world of Computational Fluid Dynamics.

I came across a question on a social media site about how to know when the absolute maximum ratings for a component have been exceeded? In other words, how do you identify components that are stressed due to power dissipation, increase in junction te...

As a developer, you would have often used regular expressions, (\.[a-zA-Z]{2,3}), in your code to search, extract, or replace words in a string. Whether it is C++, Java, or Python, you can use regex in every programing language to match any characte...

When designing a PCB layout, all the constraints and design rules must be followed to avoid design issues and ensure that the board works as intended. Constraints are rules that you apply to different objects in your design, nets, and XNets to ensur...

So, if you are an electronics design program manager or team manager, it’s unlikely that you work directly with any design tools, such as System Capture. However, you might still want quick access to ECAD data, including project lists, Live BOM...

Cadence OrCAD and Allegro 17.4-2019 Hotfix 019 was rolled out in mid-July and is now available for download. In this update, we bring to you many new and enhanced features across multiple technological areas, fixes for customer-reported bugs, ...

When time and quality are at a premium and you are in a hurry to meet a tight schedule, access to 5000 tried and tested TI-PSpice models across 100 categories, not to mention the 4000 test circuits, definitely gives you the edge you needed. You can q...

Picking up from where we left off in the previous post , let’s look at some more new and interesting changes made in Hotfix 019. As you might already know, Allegro® System Capture is available both for designers who work alone, in small tea...

“The only constant in life is change” nowhere is this adage truer than in the world of software. Updates, releases, patches … They are a part of our lives as experts work behind the scenes to constantly improve and fine-tune what w...

Boards and Packages are getting extremely complex and large; what used to be considered large with millions of objects is now close to 100s of millions of objects. Traditional rendering on CPU of such large and complex designs is not scalable for tod...

The Download Manager user interface has been revamped in 17.4-2019 HotFix 019. Various new features are integrated to enhance user experience and efficiency. The latest release of Download Manager delivers modern UI architecture with a scope for future enhancements...

The HotFix 019 (QIR 3, indicated as 2021.1 in the application splash screens) update for Release 17.4-2019 of OrCAD and Allegro products is now available at Cadence Downloads. This blog post contains important links for accessing this update and introduces s...

IPC-2581 ensures efficient PCB design data transfer and brings advanced capabilities to extract all the required data for manufacturing and assembly. This includes netlist, test pad information, artwork, drill data, bill of materials, test files, and design variants. While exporting data, you can choose to suppress any information which is not needed for fabrication, assembly, testing, or procurement
