EDACafe Weekly Review February 26th, 2015

New Ascent Lint with DO-254 Compliance Testing

On February 25 we announced the 2015 release of Ascent Lint for comprehensive RTL analysis and rule checking. The new version for 2015 delivers enhanced support for the SystemVerilog language, DO-254 policy files for compliance testing of complex electronic hardware in airborne systems, deeper rule coverage and easy configurability. We believe it is the industry’s fastest-performance, highest-capacity and most precise Lint solution in the market.

Additional enhancements and new features for Ascent Lint include:

  • Enhanced VHDL finite state machine (FSM) handling for deeper analysis
  • 17 new VHDL and 12 new Verilog lint rules that ensure design code quality and consistency for a wide range of potential issues
  • Lower noise in reporting of design issues

Art Critic Robert Hughes produced a difficult documentary in 1980 that assaulted the mind and eye with images and ideas associated with modern art, the visual arts of the 20th century. Now 35 years later and well into the 21st century, Hughes’ concept of things that are both new and shocking is more compelling than ever. This little essay is peppered with a few things which I think encapsulate The Shock of the New circa 2015.

Let’s start with the upcoming Trip to Mars. Last month it was announced that 100 people had been chosen from a field of 200,000 candidates worldwide to start to prepare for a one-way trip to Mars, slated to launch in 2024. Come’on, really? A one-way trip to Mars? It may sound like a way-cool nod to someone’s pluck and courage to be chosen for the trip, not to mention the technological tour de force needed to get the vehicle and passengers there — but do we honestly want to admire anybody whose death wish includes a long freaky trip to a planet that cannot support any of the life forms we’re aware of, including us? Really?


In a recent phone call, Silicon Cloud co-founder and CEO, Mojy Chian asserted that the IoT has inspired a new set of initiatives from his lively startup enterprise.

“If you look at the Internet of Things in its entirety, it includes the transmission, aggregation, processing, cloud services and so on.” Chain said, “But it all starts with the nodes, the endpoints, which are the sensors.

“Today we are positioning Silicon Cloud to provide a design-enablement infrastructure for the IoT, a large part of which is the chip design. But now we are extending our services to include design tools for sensors, concentrating on the node itself, and providing a complete infrastructure for node design enablement. We don’t design the semiconductor or the sensor, of course. We provide the design enablement for others to use to design these things.”

The Importance of DVCon and Why Breker Will Be There

Most of the time when we blog about upcoming conferences, report live from an ongoing show, or summarize one that’s just finished, we see a significant spike in readership. Clearly our followers want to keep up with what’s happening in trade shows, conferences, and other industry events. It may also be the case that tighter travel budgets have reduced the ability to attend conferences in person, driving all the more interest in reading the news from the field. A few weeks ago, we discussed DesignCon and explained how it had evolved to include almost no verification content.

Next week is the annual Design and Verification Conference (DVCon) in San Jose, an event that we have covered in considerable detail in several popular posts in the past. As we have discussed, this conference has become the main way to keep up on what’s happening in the ever-changing world of functional verification. We encourage you to check out their Web site and the complete program. The topics include the UVM, SystemVerilog, SystemC, code generation, multi-language, mixed-signal, formal techniques, coverage metrics, and low-power verification.

Xilinx-Tcl-StoreTaking a cue from the open-source community, Xilinx has launched a Tcl Store that aggregates Tcl scripts contributed by the greater development community to expand the capabilities of the Vivado® Integrated Design Environment.

All Tcl scripts contributed to the Xilinx repository are free and re-distributable under an open-source license that is based on the Berkeley Source Distribution (BSD) model. Vivado users can now download apps from the Tcl Store that include practical bundles of Tcl scripts that act just like Vivado commands, including an app that can integrate Aldec Active-HDL and Riviera-PRO tools within the Vivado design flow.

To take advantage of these pre-packaged Tcl Script apps within Vivado, users can access the Tcl Store via the Vivado IDE “Tools” menu. For the rest of this article, visit the Aldec Design and Verification Blog.

What inspired you to become an engineer?

This week, February 22-28, we celebrate National Engineers Week in the US to recognize the contributions to society that engineers make. During this time, there is added emphasis in schools on the importance of learning math, science, and technical skills.

I work with Generation STEAM, a group organized by the SYN Shop MakerSpace and the Henderson district library to create a series of STEM (Science, Technology, Engineering, [Art], and Math) classes that are free to the public. For my part, I’ve had the privilege of teaching a basic electronics class for kids a few Saturdays this year – and it’s been a blast. Our hope is that we are encouraging a few young people to follow the path of engineering.
