Time To Rethink Memory Chip Design And Verification


It’s no secret to anyone that semiconductor development grows more challenging all the time. Each new process technology node packs more transistors into each die, creating more electrical issues and making heat dissipation harder. Floorplanning, logic synthesis, place and route, timing analysis, electrical analysis, and functional verification stretch electronic design automation (EDA) tools... » 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

Getting Ready For An Efficient Shift To PCI Express 6.0 Designs With Optimized IP


PCI Express (PCIe) 6.0 technology with key changes will bring about challenges that high-performance computing, artificial intelligence, and storage system-on-chip (SoC) designers will face. This article provides designers a summary of the major changes and how they can be handled to ensure a smooth and successful transition to PCIe 6.0. The three major changes in PCIe 6.0 that designers nee... » read more

Early Detection Of Reset Domain Crossing Errors


Many aspects of system-on-chip (SoC) designs are growing, including the numbers of gates, memories, clock domains, reset domains, power domains, on-chip buses, and external interfaces. A recent blog post focused on reset domain crossings (RDCs) and the requirements for effective pre-silicon verification of these trouble-prone structures. If properly applied, a solution meeting these requirement... » read more

Meeting Fundamental Interface Requirements For Camera And Display With Integrated MIPI IP


Cameras and displays are used in cars, industrial and medical devices, smartphones and other mobile devices, and machine vision applications. Over the years, the required data for high resolution videos and images have increased, forcing camera and display SoCs to process more complex visual data. The MIPI Alliance offers a portfolio of camera and display interfaces that deliver differentiation... » 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

112G SerDes Modeling And Integration Considerations


The ever-increasing demand for compute power and data processing in accelerators, intelligence processing units (IPUs), GPUs, as well as training and inference SoCs is driving the adoption of 112G SerDes PHY IP solutions. Ensuring a reliable Ethernet link and efficient integration are the most essential requirements that designers need to meet. IBIS-AMI modeling can help predict SerDes link per... » read more

The Challenge Of Balancing Performance And Accuracy For Advanced Node Timing Signoff


As process nodes shrink, complexity, cost and overall risk expand. Process variability that once was once acceptable now becomes a critical item as operating voltage decreases. Simply adding design margin makes the chip non-competitive. Physical effects that were once ignored now become critical as well. The impact of interconnect can no longer be modeled based on simple circuit topology. Layou... » read more

Effective Clock Domain Crossing Verification


As chips grow ever larger and more complex, gate count and amount of embedded memory grow dramatically. The number of clock domains is also increasing steadily. Several dozen different clocks are common in today’s chips, with some designs having more than a thousand domains. There are several reasons for this explosion: Multiple external interfaces with distinct clock requirements Lic... » read more
