Cracking The Mixed-Signal Verification Code


Rapid digitization in IoT, automotive, industrial, and communication industry segments are fueling semiconductor industry growth. This growth follows the “More than Moore” paradigm, where new design starts are spread across mature to advanced manufacturing nodes based on end-application targets. With this digitalization, data has become the most valuable resource. Mixed-signal designs pl... » read more

Improving Library Characterization Quality And Runtime With Machine Learning


By Megan Marsh and Wei-Lii Tan Today’s semiconductor applications, ranging from advanced sensory applications, IoT, edge computing devices, high performance computing, to dedicated A.I. chips, are constantly pushing the boundaries of attainable power, performance, and area (PPA) metrics. The race to design and ship these innovative devices has resulted in a focused, time-to-market-driven e... » read more

Next-Generation Liberty Verification And Debugging


Accurate library characterization is a crucial step for modern chip design and verification. For full-chip designs with billions of transistors, timing sign-off through simulation is unfeasible due to run-time and memory constraints. Instead, a scalable methodology using static timing analysis (STA) is required. This methodology uses the Liberty file to encapsulate library characteristics such ... » read more

Digital IC Bring-Up With A Bench-Top Environment


One of the hottest markets for IC today is artificial intelligence (AI). The designs for AI chips are also among the largest and most complex, with billions of transistors, thousands of memory instances, and complex design-for-test (DFT) implementations with unique bring up and debug requirements. At this point, the volume of new AI chips is relatively low, but time-to-market is of paramount im... » read more

Synthesizing Computer Vision Designs To Hardware


Computer vision is one of the hottest markets in electronic design today. Digital processing of images and video with complex algorithms in order to interpret meaning has almost as many applications and markets as there are uses for the human eye. The biggest problem that designers face is that the computer vision system requirements and algorithms change quickly and often. Even the targ... » 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

Making Declarative Modeling Modular: Portable Stimulus Introduces Dynamic Constraints


Naturally, Accellera’s Portable Stimulus Standard (PSS) supports the powerful capabilities of advanced verification techniques that are well-known in the industry today, including object-oriented composition and constrained-random stimulus. But the PSS also supports a new constraint capability, called dynamic constraints. Dynamic constraints support the critical mission of the PSS by makin... » read more

Interface DRC Can Streamline Chip-Level Interface Physical Verification


In most design companies, the chip-level physical implementation teams responsible for design floorplanning in place and route (P&R) environments also manage top-level physical verification from the early floorplanning stages through tapeout. In early floorplanning stages, blocks placed in the chip-level floorplan are usually still under development. Merging these incomplete blocks with the... » read more

How Automotive ICs Are Reshaping Semiconductor Test


The growth of a new IC market creates ripples along the entire supply chain. Today, we see the semiconductor industry reacting to the needs of the growing automotive IC market, including the development of new IC test tools and methods. The automotive IC market is far and away the fastest growing end-use market with 15% CAGR (according to IC Insights). It is also seeing many new players. Mar... » read more

A Reliability Baseline Is Essential For Today’s Complex IC Designs


Design rule checking (DRC) represents a common platform by which we can all compare relative rule complexity. The industry expectation is that all foundries will provide complete DRC and layout vs. schematic (LVS) rule decks at all process nodes for the successful tape-out of IC designs. However, not only are DRC operations growing significantly (Figure 1), but the scope of the rules needed to ... » read more
