Hyper-Convergence Is The New Normal For Digital Implementation


The era of smart-everything has led to a surge in the need for semiconductor devices across a myriad of traditional and novel applications. These applications demand high performance yet energy-efficient compute over blazing-fast networks to service trillions of edge devices that are constantly consuming and generating large amounts of data. This surge has invigorated system architects to innov... » read more

Tape Out On Time With Demand Signoff DRC In P&R


Physical characteristics of devices have become progressively more complex even as design companies pack more devices on each die. Combining these characteristics with ever more demanding chip power, performance, and area (PPA) goals not only result in increased resource utilization but also challenge existing tools/flows/techniques. Adding on-demand signoff-quality DRC verification inside P&R ... » read more

Best 112G SerDes IP Architecture


Real world operation of a serializer/deserializer (SerDes) in a hyperscale data center is very demanding and requires robust performance in challenging conditions such as multitude of channel insertion loss, extreme temperature cycles, different types of packages with different trace lengths and discontinuities, etc. Hence, meeting interference tolerance (ITOL) and jitter tolerance (JTOL) compl... » read more

Cell Library Verification Using Symbolic Simulation


Standard cell libraries have been a mainstay of chip design for many decades since the inception of logic synthesis and composition methodologies. Cell library IP typically contains Verilog models describing the cell functionality, schematic derived transistor level netlists, place and route views, physical layout views, post-layout extracted netlists as well as characterized timing and power m... » read more

IP Solutions For A Data-Centric World


We’re in an era of sizeable growth in data and compute demand, along with increasing global data traffic. As a result, high-performance computing, data communications, networking, and storage systems are taking center stage in many application areas, driven by newer applications such as analytics, artificial intelligence (AI), genomics, and simulation-intensive workloads. Power efficiency, hi... » read more

AI Testing: Pushing Beyond DFT Architectures


Every day, more applications are deploying artificial intelligence (AI) system to increase automation beyond traditional systems. The continuous growth in computing demands of AI systems require designers to develop massive, highly parallel AI processor chips. Their large sizes and types of applications have a significant impact on their design and test methodologies. With thousands of repeated... » read more

Hyperconnectivity, Hyperscale Computing, And Moving Edges


As described in “The Four Pillars of Hyperscale Computing” last year, the four core components that development teams consider for data centers are computing, storage, memory, and networking. Over the previous decade, requirements for programmability have fundamentally changed data centers. Just over a decade ago, in 2010, virtual machines would compute user workloads on CPU-centric archite... » read more

Addressing IC Hyperconvergence Design Challenges


Recently in an article titled “A Renaissance for Semiconductors,” my colleague Michael Sanie highlighted some of the trends that are driving next-generation product development. He detailed how designs targeting new applications are innovating through a combination of advanced process node technologies and heterogeneous integration of stacked die/3D/2.5D systems. Additionally, advanced vert... » read more

Know Your Own Power, Early And Accurately


By Taruna Reddy and Vin Liao Chip designers have always had to balance timing and area. Everyone wants a design as fast as possible and as compact as possible, but these two goals are usually in conflict. For the last couple of decades, minimal power consumption has been a third goal, often of equal importance. Some of the biggest drivers for the semiconductor industry are battery operated p... » read more

DFT For SoCs Is Last, First, And Everywhere In Between


Back in the dawn of time, IC test was the last task in the design flow. First, you designed the chip and then you wrote the functional test program to verify it performed as expected after manufacturing. Without much effort, some portion of the functional test program was often reused as the manufacturing test to determine that the silicon was defect-free. Fast forward to today and things ha... » read more
