Developing high-reliability FPGAs for DO-254

August 25th, 2015 by Louie De Luna

Developing-FPGAs-for-DO-254You have been developing FPGAs for a long time, and you know your designs from top to bottom. You know every interface protocol, configuration and optimization. You can visualize your timing diagram like you can visualize your upcoming vacation in Hawaii. You can manually write down your memory mapping accurately while under oath. You can pinpoint all CDC paths and emulate metastability in your mind. You are confident that your designs are fault-tolerant and will function as intended. You are the master of your domain.

But… can you bet your life on it?

Are you willing to bet your life on your designs? What about the lives of the thousands of passengers sitting on the airplanes where your FPGA design is installed? How certain are you that it won’t fail in the field? If it were to fail, can it resume normal operation safely and timely? Not just MOST of the time, but EVERY time?

The Pythonic Tonic: Miracle cure or Snake-oil?

May 20th, 2015 by Satyam Jani

python-logoPython is making inroads in the EDA landscape, but is all the hype justified? Do the productivity benefits of a dynamic language translate to gains for real-world development for ASIC and FPGA designs? Chris Higgs of Potential Ventures will be onsite at DAC to share his experiences using Python and Aldec Riviera-PRO to take products from idea to production quickly.

Chris recently wrote a Guest Blog on the topic, visit the Aldec Design Verification Blog to learn more.

So, what does a vendor-independent simulator look like?

May 15th, 2015 by Satyam Jani

blog_independent_simulator_051515Well, the short answer to that is, “Awesome”. Perhaps, as the product manager of a simulation tool, I’m a little biased. Not to discount the challenges that FPGA design teams face on daily basis, particularly with device complexities now going through the roof.

There was a time, not so long ago, when using a single FPGA device from one vendor was not so uncommon and simulation and verification were quite interchangeable terms. However in recent years, with the development of more complex FPGAs and an even more complex design process involving the use of IPs, VIPs and third party models , the need for vendor agnostic tools for simulation and verification has become more evident.

How Can Verification IPs Help the SoC Testing Process?

How to use VIPs In Practice

Let’s assume that we are designing a new system on chip (SoC) which contains a processor and memory controller, as well as analog and digital peripherals like Ethernet, USB, 1-Wire and JTAG controllers.

Allow me to describe a typical verification process, and explain why I recommend the use of Verification IPs within the testing process.

Are Metastability Monsters Lurking Beneath the Surface?

March 5th, 2015 by Stan Hanel

taming-mestastability-monstersEvery engineer and technician is aware of Murphy’s Law: “Anything that can go wrong will go wrong”.

The law appears when your elegantly-sculpted hardware and artfully-styled software code bang up against the real world of transition delays and timing requirements.

Over time, designers and trouble-shooters develop a healthy respect for Mr. Murphy and begin to anticipate when he is looking over their shoulder, learning “best practices” for recurring design problems.

The toughest design problems to trouble-shoot are ones that fail intermittently. A hidden flaw seems to pop up randomly with no certain pattern or definable cause.

Xilinx Tcl Store Integrates Aldec Simulators with Vivado IDE

February 24th, 2015 by Stan Hanel

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?

February 24th, 2015 by Stan Hanel

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.

Scaling the “Internet of Things”

January 21st, 2015 by Stan Hanel

Internet-of-thingsHappy New Year!

January brought an unseasonably warm wave of weather to Las Vegas as International CES converged on the city this month.

The size and scope of this worldwide consumer electronics tradeshow continues to grow each year with new products and industries on the rise, now driven by a phenomenon called the “Internet of Things” (IoT).

Shawn Dubravac, Ph.D., Chief Economist and Director of Research for the Consumer Electronics Association (CEA) kicked off the event by presenting a summary of his new book, “Digital Destiny”.

Spec-TRACER now directly integrated with IBM DOORS

December 10th, 2014 by Louie De Luna

Spec-TRACER-DOORS-IntegrationIn response to user feedback, Aldec has developed a direct integration between IBM® Rational ® DOORS ® and our requirements management tool, Spec-TRACER™, to enable users to extend the traceability data in DOORS to FPGA design and verification elements.

Aldec has a strong 30-year+ history of asking and listening to the engineering community and we’re proud to say, thanks to your requests, that Spec-TRACER 2014.12 featuring direct integration with DOORS… is now available to test drive.

Below you’ll find an overview of the Spec-TRACER/DOORS tool flow. DOORS remains the main source and environment for managing board requirements and other higher level requirements, while Spec-TRACER remains the main source and environment for managing FPGA requirements, conceptual design data, detailed design data, test cases, test procedures, test results, traceability data and review activities. Spec-TRACER also remains the main source for generating all the pertinent reports for the FPGA project such as requirements documents, verification procedures, test results, impact analysis reports and project status reports.
