PCB Design Blog

So far 2013 has been a great year to explore the creative drawing aspects in DxDesigner.  I’ve been ignoring my blog writing but I’ve been drawing several new schematics and updating many of our older reference designs with the new capabilities in DxDesigner 7.9.4. In the example below, an entire new design was created, from a new library symbol set, finding and drawing a reference schematic

The World-Class Executive’s Five Year Survival Plan Throughout successive peaks and troughs of the business climate, there are always opportunities to succeed over competitors in the market. The more volatile the electronics industry becomes, the greater the opportunities, but the more difficult it may seem to address them. Today, with business being challenged in so many areas, and with such key changes

Don't Fear the VM

Posted by Randall Myers

While recording a how-to video about placing parts on a schematic, one part is showing off the hyperlink to the datasheet.  That is moderately cool in the hardware designer circles, but what happened when I clicked the link was beyond cool.  To see the whole picture, I have a Windows-Dell and a MacBook Pro next to each other on my desk.  I use virtual machines (VM) to keep all the various flavors of

Last week at DesignCon 2013, I provided an Analysis Anchored to Reality presentation of the highlighting and validating the new features of HyperLynx 9.0. Teledyne LeCroy, Molex, CCN, and Picosecond Pulse Labs partnered with us to provide measurement equipment, hardware to test, and a pattern generator for this demonstration. We started off with a correlation study so customers could see that the analysis

Extreme Chicken & Egg

It is always interesting to hear about those companies who have actually taken radical action to succeed, rather than just talking about it. Seeing changes in market demand and hearing how new tools can help, they jump in and address the challenges head-on. Making the changes creates for these companies something that in a real business sense, sets them apart from their peers. Such a success story I

The Mentor Graphics support group has been busy this past year creating several webinars and support videos on DxDesigner.  If you’re subscribed to the SupportPro Newsletter, you may have noticed eight new videos posted from our support team on using DxDesigner. These videos are also available at this link: http://supportnet.mentor.com/reference/tutorials with your SupportNet account. SupportNet Recently

Over the past 16 years I’ve had the pleasure of being part of the development of HyperLynx and am excited about the latest release, HyperLynx 9.0 as we are simultaneously celebrating its 25th birthday and 10th year with Mentor Graphics. HyperLynx was founded in 1988 when cell phones were the size of a lunch box, FPGAs were just hitting the streets with a Xilinx 2064 touting 64 logic cells, VHDL and

Creating a Cover Sheet with Links

Posted by Gary Lameris

Gary Lameris

A few weeks ago I was visiting a nearby customer to demonstrate the powerful ELDO SPICE simulator as an add-on to our HyperLynx Analog simulation lauchpad. To navigate through the schematic, I clicked on the arrows I use for links on the cover page to jump to the page for simulation. After the demo was complete the customer asked me, “You clicked on an arrow on the table of contents page and ended

After years of pooh-poohing AMD, Intel had to admit you could get more data throughput switching to a high-speed serial approach. Let’s say high-speed serial is in the 1 to 10 Gbps range per lane, and use PCIe as an example. This is where the benefits become irresistible and the behavior becomes unexpected according to the previous rules of layout design. The PCIe specification helps define the different

How much stitching do I need?

If signal integrity engineers had the power to make their jobs as easy as possible, every signal in an electronic device would have its own coaxial cable to connect driver to transmitter.  But then electronics would be the size of buildings again and certainly wouldn’t fit in your pocket.  So instead, we try to cram as much stuff as possible onto a little PCB and make it work at 100s and 1000s

Fix The Problems, Not The Symptoms!

Posted by Michael Ford

Michael Ford

Fixing problems can seem hard, there is always a momentum resisting change. Is it better though, to spend time and effort to fix the symptoms of the problem? Quite honestly, no. The UK had a lot of rain recently, but, the growing season is coming around again and the greenhouse is only partially complete, so the week-end was spent outside digging in the mud, again. The next door neighbour comes along,

Pick a layer and stick with it

Posted by Patrick Carrier

Patrick Carrier

One of the nice things about newer, faster busses like DDR3 and DDR4 is on-die termination.  They are nice because you don’t have a bunch of components clogging up your routing layers, and I would say more importantly, it limits your required layer transitions which can help make your boards quieter.  So take advantage of the fact that you don’t have to route out to a terminator and try

In the past I have blogged about crossing splits in reference planes.  This is probably the most glaringly obvious of reference plane changes, and will of course result in radiation from the signal.  But another type of reference plane change which is more common, and usually much less avoidable, is when a signal transitions layers through a via.  In such a case, the reference planes will change and

Much of the your end PCB product costs can be directly influenced by the parts selected up front during the schematic capture phase of the design process. When you incorporate information into the designer’s part selection interface such as preferred part status, compliance, and/or obsolescence, you can reduce the work and rework of designs thus saving you additional costs. Today, it is a challenge
