Not All There: Heterogeneous Multiprocessor Design Tools


The design, implementation, and programming of multicore heterogeneous systems is becoming more common, often driven by the software workloads, but the tooling to help optimize the processors, interconnect, and memory are disjointed. Over the past few years, many tools have emerged that help with the definition and implementation of a single processor, optimized for a given set of software. ... » read more

Verification And Test Of Safety And Security


Functional verification can cost as much as design, but new capabilities are piling onto an already stressed verification methodology, leaving solutions fragmented and incomplete. In a perfect world, a semiconductor device would be verified to operate according to its complete specification, and continue to operate correctly over the course of its useful life. The reality, however, is this i... » read more

The True Cost Of Software Changes


Safety and security are considered to be important in a growing number of markets and applications. Guidelines are put in place for the processes used to develop either the hardware or the software, but what they seem to ignore is that neither exists in a vacuum. They form a system when put together. Back when I was developing tools for hardware-software co-verification, there were fairly co... » read more

Power/Performance Costs Of Securing Systems


For much of the chip industry, concerns about security are relatively new, but the requirement for protecting semiconductor devices is becoming pervasive. Unfortunately for many industries, that lesson has been learned the hard way. Security breaches have led to the loss of sensitive data, ransomware attacks that lock up data, theft of intellectual property or financial resources, and loss o... » read more

Software-Defined Hardware Architectures


Hardware/software co-design has been a goal for several decades, but success has been limited. More recently, progress has been made in optimizing a processor as well as the addition of accelerators for a given software workload. While those two techniques can produce incredible gains, it is not enough. With increasing demands being placed on all types of processing, single-processor solutio... » read more

A Highly Wasteful Industry


The systems industry as a whole is not concerned about power. I know that is a bold statement, but I believe it to be true. The semiconductor industry is mildly concerned, but only indirectly. They care about power because thermal issues are limiting the functionality they can squeeze onto a chip, or in a package. Some users, such as data center operators, claim to care about power because i... » read more

IP Becoming More Complex, More Costly


Success in the semiconductor intellectual property (IP) market requires more than a good bit of RTL. New advances mandate a complete design, implementation, and verification team, which limits the number of companies competing in this market. What constitutes an IP block has changed significantly since the concept was first introduced in the 1990s. What was initially just a piece of RTL (reg... » read more

Holistic Power Reduction


The power consumption of a device is influenced by every stage of the design, development, and implementation process, but identifying opportunities to save power no longer can be just about making hardware more efficient. Tools and methodologies are in place for most of the power-saving opportunities, from RTL down through implementation, and portions of the semiconductor industry already a... » read more

AI Adoption Slow For Design Tools


A lot of excitement, and a fair amount of hype, surrounds what artificial intelligence (AI) can do for the EDA industry. But many challenges must be overcome before AI can start designing, verifying, and implementing chips for us. Should AI replace the algorithms in use today, or does it have a different role to play? At the end of the day, AI is a technique that has strengths and weaknesses... » read more

Can AI Write RTL?


Just a few months ago, generative AI was just a promise about what would be possible in the future. Today, nearly everyone with an ounce of curiosity has tried ChatGPT. Most people appear to be somewhat impressed with what it can do, but at the same time see the limitations that it has. As Dean Drako, founder of several companies, told me: "Recently, I needed to write a patent. I described t... » read more
