PADS Desktop PCB Design

Discussions on the present, future capabilities and value of the PADS PCB flow.

27 October, 2014

We all know creating and managing part libraries is not an easy task; it’s time consuming, error prone, and requires constant maintenance.  If you have ever tried using a library that you built with one design tool in a different design tool, you probably got an additional set of problems, starting from schematic parts that don’t reference the correct footprint name, to schematic parts that don’t have correct part numbers, and missing information. And how about L libraries that are provided with different design tools? Too often they’re low quality and unusable, causing consistency and integrity issues down the road.

Over the past year working alongside the PADS engineering team, I’ve identified three elements that can reduce some of those issues, and make the library creation and maintenance a lot easier.

elements

#1 – Your design tool

The first thing that impacts the complexity of your library creation process is your chosen design tool. Having a design tool that allows easy and efficient library management is really what you’re searching for. For example, having the design tool support a central library concept, can save you time and eliminate errors and duplications, by gathering all your library information in a centralized location. Also, you want your design tool to have a really efficient and high-quality part creation wizard, to minimize part creation time and manual work.

#2 – Library translation

Find a good solution for translating old libraries into your current design tool, to avoid having incorrect parts in your library. A common problem people have with translated libraries is mismatches between schematic and layout data. Not aligning this information can cause consistency issues in your library, so you need to make sure you choose the correct part name, ref-des and cell name, and apply it in both sides. PADS for example, along with the translator, provides a script to automatically do this process for you. The result is reliable and complete library data.

#3 – Well-documented component properties

The third element is what really takes stamina! Make sure that for every part you create, you always take the time to update the important component properties – not just for now, but for all stages of the design flow. For instance, try to keep all the information related to the identity of the part (part number, manufacturer name), and always make sure to include links to part datasheets to have easy access to additional information about each part. It also can be helpful to keep information such as voltage for later use in simulation. Keep in mind that the more you put into the quality of the parts you create now, the easier it will make each and every stage of the design cycle, and with less issues down the road – from search and selection of parts, to layout design, simulation, and even manufacturing.

Maximize your Power and Efficiency with PADS Interactive Placement and Routing: For the engineer doing desktop PCB layout, efficiency is important. You don’t want to waste precious time fighting with your PCB tool, and you don’t want to end up with lousy results because you and your tool weren’t getting along. Mentor Graphics PADS provides an efficient, high-productivity interactive placement and routing environment that lets you get great results quickly. Download the White paper now.

In today’s competitive marketplace companies cannot afford to have PCB production delayed because of slivers, unintended copper exposed by soldermask, testpoint-to-testpoint spacing, or other issues that should be identified and solved early in layout and long before manufacturing. Catching DFM issues at the design stage is critical because, at each successive step of the production process, the cost of rectifying a problem increases tenfold over the previous step.  This paper offers 100 ways to analyze for design for manufacturability in the PADS PCB design flow.

This week I had the pleasure of  meeting and talking with engineering students along with our recruiting staff at the NC State Engineering Career Fair! This 2 day event is sponsored by the NCSU College of Engineering and is held yearly.

NCSU_CF

This event draws talented engineering students from colleges all over the Carolinas and beyond. The attendance was unbelievable and the students were dressed to the nines with polished resumes in hand. I had the pleasure of talking to students that ranged from freshman looking for internship opportunities to expectant winter and spring graduates looking for their dream job. More than 360 employers filled nearly every room at the McKimmon Center with displays and recruiting staff eager to meet candidates and fill immediate job openings and internships.

NC CF bannerUp next, the Mentor recruiting team is on their way to the Syracuse University Engineering Career Fair to find more great engineering talent. If you are unable to attend an engineering career fair in your area this fall be sure to visit us at mentor.com/careers to learn all about the exciting job openings and internship opportunities that are available here at Mentor Graphics.

bellaag_logo“Most cattle are healthy most of the time; it’s the ones that aren’t that you need to know about.”

We can never overstate the importance of cattle in our lives. Cows are not raised just for their meat, milk, and leather. The fact is, there are more products produced from cattle that are used in our everyday lives than many of us can fathom. Medical and pharmaceutical companies for example, use insulin from the livers of cows for diabetics.

Cattle, as living creatures, are healthy most of the time; it’s the ones that aren’t that you need to know about. This is where Bella Ag comes in. Bella Ag has developed a device called the 3.0 Bolus. The Bolus is a temperature monitoring collection system that enables cattle operators to detect health issues early. The collector wirelessly transmits the data it collects to a wireless gateway. Data is collected and processed with Bella TempSoft software and is used to establish a baseline for every individual cow.

LI Graphic_Bella AG

The Bella Ag Bolus wirelessly monitors the cattle’s temperature and automatically sends alerts that enable cattle operators to catch illnesses like mastitis, metritis and pneumonia 3 to 5 days sooner. This Patent Pending design utilizes the latest in micro transceiver technology and is designed for optimal performance from the inside of the animal out.

The PCB’s within Bella Ag’s advanced electronic system were designed using PADS PCB Design tools. Bella Ag’s CTO, Stephen Weilnau stated that “The PADS suite gives us a real value added tool that enables us to be small but work big”. Bella Ag collaborates with various independent PADS contractors that work on different projects.  Weilnau stated that, “As a small shop we found it useful to have access to the same development tools, be able to open the working files, provide much needed feedback, and even make modifications later when parts are obsolete.

Bella Ag Systems patented technology is currently running in 11 countries around the world, shaping the future of animal health and the agriculture industry.
