Toward Cross-Layer Resilience


Connected devices are everywhere, and the numbers are growing by orders of magnitude. There are 7 billion people on the planet, but there are expected to be many more billions of connected devices. Each person may have dozens of devices with multiple chips, and those will be connected through infrastructures filled with thousands of additional chips. The problem is that as everything gets c... » read more

Abstraction Aging


During the course of doing interviews for my article on system simulation and abstraction, I spoke to several people who, just like myself, had started their career pushing abstraction. At the time, we were all frustrated that the industry didn't move fast enough. The advantages of abstraction appeared to be so clear. Everyone developed slides showing that the cost to fix bugs increased the fur... » read more

Wednesday At DAC 2018


Wednesday starts with a visionary talk followed by a keynote. The Visionary talk was given by Chidi Chidambaram, VP of engineering for Qualcomm, and looked at 'Challenges to Enable 5G System Scaling.' "We have to start taking a system view rather than just following technology and at the same time we have to get concerned about durability," he said. "Mobile will continue to be the leader becaus... » read more

Raising The Bar On Flat CDC Verification With Hierarchical Data Models


By Ashish Hari, Aditya Vij, and Ping Yeung Traditionally, clock domain crossing (CDC) verification at the SoC level has relied on flat simulation runs. But flat CDC verification has run out of gas. Largely because of the increase in the number of asynchronous clocks in larger, faster, more complex designs. Flat CDC runs are too performance intensive, time-consuming, and result in high noise.... » read more

The Skies Over EDA Are Finally Cloudy


EDA companies have been talking for years about providing access to their tools in the cloud, including more articles than I can count with titles about the EDA forecast being cloudy, clouds on the horizon, and so forth. The title of this post continues the dubious tradition of cloud-based puns, but there’s no future tense involved. Recent announcements from several EDA companies make it appe... » read more

SoC FPGAs And HW/SW Co-Simulation


Heterogeneous System on Chip (SoC) devices like the Xilinx Zynq 7000 and Zynq UltraScale+ MPSoC combine a high-performance processing system (PS) with state-of-the-art programmable logic (PL). This combination allows a system to be architected to provide an optimally balanced single-chip software/hardware solution. However, all too often, the integration between the PS and PL takes place late... » read more

FinFET ASICs: It Takes A Platform


Sophisticated, specialized ASIC technology is making an impact on the everyday world around us. Whether it’s a gadget you can have a conversation with, a car that will take over driving from time to time, or internet speeds that seem impossibly fast, there is likely sophisticated custom silicon present as a critical enabling technology. Plenty has been written about advanced ASICs for network... » read more

DAC 2018: System Design, Cloud And Machine Learning


This marks the 10th DAC that I have covered as a blogger. At DAC 2008 in Anaheim, the industry had just come together behind the SystemC TLM 2.0 standard to enable virtual platforms, finally getting to model interoperability. System design is the common thread that is also present in this year’s DAC in 2018 in San Francisco. But a lot has changed. Big data analytics, artificial intelligence a... » read more

Tuesday At DAC 2018


The morning starts with the Accellera Breakfast. Accellera has made some significant progress this year and we can expect to hear about the approval of the Portable Stimulus 1.0 specification later in the conference as well as the initial release of SystemC CCI as well as a proposal for the creation of an IP Security Assurance Working Group, which will discuss standards development to address s... » read more

Monday At DAC 2018


DAC #55 started with rumors flying. Will this be the last DAC as we know it? Is there a huge chasm forming between academia and the industry? Will DAC be able to make it in Las Vegas where there is no local interest? Of course, those who have been in the industry know that this kind of speculation happens every few years, and in the 80s, Las Vegas was a very popular location for DAC. There was ... » read more
