Why It’s So Hard To Create New Processors


The introduction, and initial success, of the RISC-V processor ISA has reignited interest in the design of custom processors, but the industry is now grappling with how to verify them. The expertise and tools that were once in the market have been consolidated into the hands of the few companies that have been shipping processor chips or IP cores over the past 20 years. Verification of a pro... » read more

Do You Trust Your IP Supplier?


How much do you trust your IP supplier, regardless of whether IP was developed in-house or by a third-party provider? And what implications does it have a system integrator? These are important questions that many companies are beginning to ask. Today, there are few methods, other than documentation, that provide the necessary information. The software industry may be ahead of the hardware i... » read more

Designing Resilient Electronics


Electronic systems in automobiles, airplanes and other industrial applications are becoming increasingly sophisticated and complex, required to perform an expanding list of functions while also becoming smaller and lighter. As a result, pressure is growing to design extremely high-performance chips with lower energy consumption and less sensitivity to harsh environmental conditions. If this ... » read more

Timing Closure At 7/5nm


Mansour Amirfathi, director of application engineering at Synopsys, examines how to determine if assumptions about design are correct, how many cycles are needed for a particular operation and why this is so complicated, and what happens if signals get out of phase. » read more

Die-to-Die Connectivity With High-Speed SerDes PHY IP


Hyperscale data center, artificial intelligence (AI), and networking SoCs have become more complex with advanced functionalities and have reached maximum reticle sizes. Designers are partitioning such SoCs in smaller modules requiring ultra- and extra-short reach links for inter-die connectivity with high data rates. The die-to-die connectivity must also ensure reliable links with extremely low... » read more

Power Management Becomes Top Issue Everywhere


Power management is becoming a bigger challenge across a wide variety of applications, from consumer products such as televisions and set-top-boxes to large data centers, where the cost of cooling server racks to offset the impact of thermal dissipation can be enormous. Several years ago, low-power design was largely relegated to mobile devices that were dependent on a battery. Since then, i... » read more

Visualizing Differences In Analog Design


Prathna Sekar, technical account manager at ClioSoft, explains the challenges of managing analog versus digital IP, including how to deal with dozens or even hundreds of versions of a schematic, and why visualization is so important for identifying changes and updates to an analog design. » read more

The Cost Of Programmability


Nothing comes for free, and that is certainly true for the programmable elements in an SoC. But without them we are left with very specific devices that can only be used for one fixed application and cannot be updated. Few complex devices are created that do not have many layers of programmability, but the sizing of those capabilities is becoming more important than in the past. There are... » read more

Hybrid Prototyping


David Svensson, applications engineer in Synopsys’ Verification Group, explains how a virtual transaction logic model can be connected to develop hardware-dependent drivers before RTL actually exists, why this is now critical for large, complex designs, and how to find the potential bottlenecks and debug both software and hardware. » read more

Tracking Re-Use Of Design IPs


Design teams have a great incentive to create design blocks or IPs that can be reused: Each time an IP is successfully reused, precious time is saved from project schedule. Of course, as easy as it sounds, achieving this goal in real life is not simple. In reality, the observation is that design libraries cannot be used as-is by multiple projects. Consider this scenario: A smart new graduate... » read more
