54th DAC Program Finalized


A DAC winter meeting held in sunny Mexico isn’t what it’s cracked up to be. (Although we did enjoy the break from this winter storms!) Everybody thinks the Executive Committee members are lounging on the beach enjoying drinks with little umbrellas in them. That couldn’t be further from the truth! In fact, I and 15 other EC members spent most of our February meetings in Puerto Vallar... » read more

HBM Upstages DDR In Bandwidth, Power


For graphics, networking, and high performance computing, the latest iteration of high-bandwidth memory (HBM) continues to rise up as a viable contender against conventional DDR, GDDR designs, and other advanced memory architectures such as the Hybrid Memory Cube. [getkc id="276" kc_name="HBM"] enables lower power consumption per I/O and higher bandwidth memory access with a more condensed f... » read more

Carving Up Verification


Anirudh Devgan, executive vice president and general manager of [getentity id="22032" e_name="Cadence's"] System & Verification Group, sat down with Semiconductor Engineering to discuss the evolution of verification. What follows are excerpts of that conversation. SE: What’s changing in [getkc id="10" kc_name="verification"]? Devgan: Parallelism, greater capacity and multiple engine... » read more

Antenna Design Grows Up


Apple’s iPhone 4 antenna issue represents a classic example of what can go wrong in modern antenna design. Put one in the wrong place, and a seemingly insignificant part can turn a cool new product into a public relations nightmare. Ever since antennas dropped out of sight, most consumers don't give them a second thought. In the 1960s, almost every home had a rooftop antenna. Fast forward ... » read more

The Ultimate Shift Left


Floorplanning is becoming much more difficult due to a combination of factors—increased complexity of the power delivery network, lengthening of clock trees, rising levels of communication, and greater connectedness of [getkc id="81" kc_name="SoC"]s coupled with highly constrained routing resources. The goal of floorplanning is to determine optimal placement of blocks on a die. But connect... » read more

Crossing The Chasm: Uniting SoC And Package Verification


Wafer-level packaging enables higher form factor and improved performance compared to traditional SoC designs. However, to ensure an acceptable yield and performance, EDA companies, OSAT companies, and foundries must collaborate to establish consistent and unified automated WLP design and physical verification flows, while introducing minimum disruption to already-existing package design flows.... » read more

Better Code With RTL Linting And CDC Verification


Automated design rule checking, or linting, has been around in RTL verification for at least a couple decades, yet still many HDL designers completely ignore this simple yet very powerful bug hunting method. Why would a busy designer need to run this annoying warning generator? The hostility against using conventional linting tools is often explained by the enormous amount of output noise, limi... » read more

Fault Simulation Reborn


Fault simulation, one of the oldest tools in the EDA industry toolbox, is receiving a serious facelift after it almost faded from existence. In the early days, fault simulation was used to grade the quality of manufacturing test vectors. That task was replaced almost entirely by [getkc id="173" comment="scan test"] and automatic test pattern generation (ATPG). Today, functional safety is cau... » read more

Bidding War On H-1B Visas?


Good help is hard to find. It's about to get harder—and more expensive. The U.S. tech industry's solution until now has been to leverage expertise from around the world, drawing top graduates and entry-level professionals under the H-1B visa program. Last year, there were 85,000 H-1B visas issued, of which 20,000 are required to hold a U.S. master's degree or higher. There are some exce... » read more

2017: Tool And Methodology Shifts


As the markets for semiconductor products evolve, so do the tools that enable automation, optimization and verification. While tools rarely go away, they do bend like plants toward light. Today, it is no longer the mobile phone industry that is defining the direction, but automotive and the Internet of Things (IoT). Both of these markets have very different requirements and each creates their o... » read more
