Too Big To Simulate?

With system design complexity set on a steady upward trajectory, there are situations in which traditional simulation just can’t keep up. The alternative—and one being used by Google, Uber, Ford, GM, Volvo, Audi and others with autonomous vehicles— is to test cars on the road and collect data for later analysis. “They're not simulating, they're just doing it all in the real world ... » read more

Overcoming The Limits Of Scaling

Semiconductor Engineering sat down to discuss the increasing reliance on architectural choices for improvements in power, performance and area, with [getperson id="11425" comment=" Sundari Mitra"], CEO of [getentity id="22535" comment="NetSpeed Systems"]; Charlie Janac, chairman and CEO of [getentity id="22674" e_name="Arteris"]; [getperson id="11032" comment="Simon Davidmann"] CEO of [getentit... » read more

What Is Fuzzing?

Fuzzing is an excellent technique for locating vulnerabilities in software. The basic premise is to deliver intentionally malformed input to target software and detect failure. A complete fuzzer has three components. A poet creates the malformed inputs or test cases.A courier delivers test cases to the target software. Finally, an oracle detects target failures. Different fuzzing techniques ... » read more

Blog Review: Oct. 26

Synopsys' Robert Vamosi provides some additional information on last Friday's massive DDoS attack against DNS provider Dyn, which hampered access to many big-name websites. On the same note, Cadence's Paul McLellan warns of the hazards default and easy-to-guess device passwords present to people far beyond the original user. Mentor's Arvind Narayanan warns that the 10nm era has changed ph... » read more

What Happened To Inverse Lithography?

Nearly 10 years ago, the industry rolled out a potentially disruptive technique called inverse lithography technology (ILT). But ILT was ahead of its time, causing the industry to push out the technology and relegate it to niche-oriented applications. Today, though, ILT is getting new attention as the semiconductor industry pushes toward 7nm, and perhaps beyond. ILT is not a next-generation ... » read more

Closing The Power Integrity Gap

Voltage drop has always been a significant challenge. As far back as 130nm, specialist tools were being used to ensure that enough local decoupling capacitance (decap) cells were inserted in addition to larger decaps implemented around the SoC. But advanced nodes are complicating matters and further increasing complexity. These technological challenges, which underlie the power, performance ... » read more

Blog Review: Oct. 19

Mentor's Colin Walls provides some tips on writing portable, reusable code. Cadence's Christine Young contends that you should never use 2.5D for characterization at advanced nodes. Synopsys' Eric Huang considers one impractical use of USB heating and the IoT. Applied's Ben Lee predicts a rapid growth in China's power device manufacturing. NXP's Joppe Bos digs into the challenges of... » read more

Side-Channel Attacks Make Devices Vulnerable

As the world begins to take security more seriously, it becomes evident that a device is only as secure as its weakest component. No device can be made secure by protecting against a single kind of attack. Hypervisors add a layer of separation between tasks making sure that one task cannot steal secrets from another. Protection of the JTAG port is necessary to prevent access underneath the h... » read more

Power Limits Of EDA

Power has become a major gating factor in semiconductor design. It is now the third factor in design optimization, along with performance, and is almost becoming more important than area. But there are limits to the amount of help that [getkc id="7" kc_name="EDA"] can provide with [getkc id="106" kc_name="power optimization"]. Power is not just an optimization problem. It is a design problem... » read more

Betting On Power And Deep Learning

Jim Hogan, managing partner of Vista Ventures, sat down with Semiconductor Engineering to talk about what investments deliver the biggest returns, how quickly, and why there are so few investors in some big growth areas. What follows are excerpts of that conversation. SE: What are you investing in these days and why? Hogan: I have about 15 active deals right now. I generally invest in thi... » read more
