Are Chips Getting More Reliable?


Reliability is emerging as a key metric in the semiconductor industry, alongside of power, performance and cost, but it also is becoming harder to measure and increasingly difficult to achieve. Most large semiconductor companies look at reliability in connection with consumer devices that last several years before they are replaced, but a big push into automotive, medical and industrial elec... » read more

Predictions For 2016: Tools and Flows


Seventeen companies sent in their predictions for this year with some of them sending predictions from several people. This is in addition to the CEO predictions that were recently published. That is a fine crop of views for the coming year, especially since they know that they will be held accountable for their views and this year, just like the last, they will have to answer for them. We beli... » read more

Reprogrammable, Reprogrammable, Reprogrammable


By Alex Grove I like FPGAs. My first experience with an FPGA was my university final year project where I demonstrated BIST with four Xilinx© 3000 devices; this was before FPGAs had JTAG built in. Filling up these devices with ViewDraw schematics required many hours in front of a terminal. Fast track to today’s advances such as Xilinx UltraScale and Vivado HLx, and I hope you would agree ... » read more

Debug: Last Bastion Of Automation


There have been a number of times when anecdotal evidence became folk law and then over time, the effort was put in to find out whether there was any truth in it. Perhaps the most famous case is the statement that verification consumes 70% of development time and resources. For years this “fact” was used in almost every verification presentation and yet nobody knew where the number had come... » read more

Finding CDC Issues Before They Find You


Clock domain crossings (CDCs) in FPGAs represent a probabilistic opportunity for failure. Functional simulation and static timing analysis tools are insufficient. Finding and addressing metastability and data incoherence around CDCs require static and dynamic analysis of FPGA designs. Aldec ALINT-PRO-CDC provides enhanced confidence that CDCs are located and fully mitigated. To read more, cl... » read more

Blog Review: Jan. 27


There's an ocean of possibilities for transistors and interconnects at the 5nm node, says Cadence's Paul McLellan – but will any of them be feasible in time? How would you design R2-D2? Mentor's Joe Hupcey III lays out what low power techniques he thinks the Star Wars droid might require. It's not all clear skies in the world of FinFETs, as Synopsys' Graham Etchells continues his series... » read more

Blog Review: Dec. 30


It's been a quiet week on the blog front. If you're looking for a bit of downtime while you enjoy the New Year, we present thoughts on what's happened this year and what may be to come from last week's System-Level Design newsletter: Editor in Chief Ed Sperling finds acquisitions and the leading edge of design defined 2015, but other changes are ahead. Technology Editor Brian Bailey obser... » read more

U.V.M. Spells Relief


Verification can be a challenging endeavor. As designs grow in size and complexity, engineers are having difficulty confirming their designs behave properly. This is where UVM may provide some relief. UVM aims to deliver an easier and more flexible way of creating robust test environments so that you can verify those difficult designs effortlessly. So what is UVM? UVM is a verification meth... » read more

Reflections On 2015


It is easy to make predictions, but few people can make them with any degree of accuracy. Most of the time, those predictions are forgotten by the end of the year and there is no one to do a tally of who holds more credibility for next year. Not so with SemiEngineering. We like to hold people's feet to the fire, but while the Pants-On-Fire meter may be applicable to politicians, we like to thin... » read more

C-Based SoC Design Flow And EDA Tools


This paper examines the achievements and future of SoC design methodology and design flow from the viewpoints of an in- house EDA team of an ASIC and system vendor. We initially discuss the problems of the design productivity gap caused by the SoC’s complexity and the timing closure caused by deep submicron technology. To solve these two problems, we propose a C-based SoC design environment t... » read more
