Week In Review: Design, Low Power


Tools & IP Synopsys unveiled a new neural processing unit (NPU) IP and toolchain. DesignWare ARC NPX6 NPU IP scales from 4K to 96K MACs with power efficiency of 30 TOPS/Watt. A single instance offers 250 TOPS at 1.3 GHz on 5nm processes in worst-case conditions, or up to 440 TOPS by using new sparsity features, which can increase the performance and decrease energy demands of executing a n... » read more

Clocks Getting Skewed Up


At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it's fraught with the most problems at the physical level. To some, the clock is the AC power supply of the chip. To others, it is an analog network almost beyond analysis. Ironically, there are no languages to describe clocking, few tools t... » read more

Unintended Coupling Issues Grow


The number of indirect and often unexpected ways in which one design element may be affected by another is growing, making it more difficult to ensure a chip — or multiple chips in a package — will perform reliably. Long gone are the days when the only way that one part of a circuit could influence another was by an intended wire connecting them. As geometries get smaller, frequencies go... » read more

Startup Funding: April 2021


April showers brought mega fundraising rounds to the semiconductor industry. In China, a mobile chipset maker looking to go public won significant funding along with partnerships with major smartphone companies. In the US, AI hardware startups are drawing interest with unique processor architectures and business models. Plus, a major test and design services company drew new investment. This mo... » read more

Week In Review: Design, Low Power


Skyworks Solutions will acquire Silicon Labs' Infrastructure & Automotive (I&A) business for $2.75 billion cash. The transaction includes Silicon Labs' power/isolation, timing and broadcast products, intellectual property, and approximately 350 employees. Silicon Labs said it will focus on its IoT business, which includes integrated hardware and software wireless platforms for multiple ... » read more

Interconnects In A Domain-Specific World


Moving data around is probably the least interesting aspect of system design, but it is one of three legs that defines the key performance indicators (KPI) for a system. Computation, memory, and interconnect all need to be balanced. Otherwise, resources are wasted and performance is lost. The problem is that the interconnect is rarely seen as a contributor to system functionality. It is seen... » read more

Integrity Problems For Edge Devices


Battery-powered edge devices need to save every picojoule of energy they can, which often means running at very low voltages. This can create signal and power integrity issues normally seen at the very latest technology nodes. But because these tend to be lower-volume, lower-cost devices, developers often cannot afford to perform the same level of analysis on these devices. Noise can come in... » read more

Is DVFS Worth The Effort?


Almost all designs have become power-aware and are being forced to consider every power saving technique, but not all of them are yielding the expected results. Moreover, they can add significant complexity into designs, increasing the time it takes to get to tapeout and boosting up the cost. Dynamic voltage and frequency scaling (DVFS) is one such power and energy saving technique now being... » read more

Maximizing Value Post-Moore’s Law


When Moore's Law was in full swing, almost every market segment considered moving to the next available node as a primary way to maximize value. But today, each major market segment is looking at different strategies that are more closely aligned with its individual needs. This diversity will end up causing both pain and opportunities in the supply chain. Chip developers must do more with a ... » read more

Low-Power Analog


Analog circuitry is usually a small part of a large SoC, but it does not scale in the same way as digital circuitry under Moore's Law. The power consumed by analog is becoming an increasing concern, especially for battery-operated devices. At the same time, little automation is available to help analog designers reduce consumption. "Newer consumer devices, like smartphones and wearables, alo... » read more
