At lower frequencies with simpler modulation, RF power amplifier (PA) designers could safely concentrate on a few primary metrics – like gain and bandwidth – and rely on relaxed margins to ensure proper operation in a range of conditions. Today’s advanced RF PA design is a different story. mmWave and sub-THz frequencies introduce… Read More

WEBINAR: Two-Part Series on RF Power Amplifier Design
On the high-speed digital design frontier with Keysight’s Hee-Soo Lee
High-speed digital (HSD) design is one of the more exciting areas in EDA right now, with design practices, tools, and workflows evolving to keep pace with increasing design complexity. With the annual Chiplet Summit and DesignCon festivities right around the corner, we sat down with Keysight’s Hee-Soo Lee, HSD Segment Lead, … Read More
WEBINAR: What It Really Takes to Build a Future-Proof AI Architecture?
Keeping up with competitors in many computing applications today means incorporating AI capability. At the edge, where devices are smaller and consume less power, the option of using software-powered GPU architectures becomes unviable due to size, power consumption, and cooling constraints. Purpose-built AI inference … Read More
Sophisticated soundscapes usher in cache-coherent multicore DSP
Digital audio processing is evolving into an art form, particularly in high-end applications such as automotive, cinema, and home theater. Innovation is moving beyond spatial audio technologies to concepts such as environmental correction and spatial confinement. These sophisticated soundscapes are driving a sudden increase… Read More
WEBINAR: PCIe 7.0? Understanding Why Now Is the Time to Transition
PCIe is familiar to legions of PC users as a high-performance enabler for expansion slots, especially GPU-based graphics cards and M.2 SSDs. It connects higher-bandwidth networking adapters and niche applications like system expansion chassis in server environments. Each PCIe specification generation has provided a leap… Read More
Webinar: RF board design flow examples for co-simulating active circuits
In part one of this webinar series, Keysight and Modelithics looked at the use of 3D passive vendor component models supporting highly accurate, automated 3D EM-circuit co-simulation of high-frequency RF board designs. Part two continues the exploration of RF board design flows for simulating active circuits on boards, again… Read More
Semidynamics adds NoC partner and ONNX for RISC-V AI applications
When Semidynamics added support for int4 and fp8 data types to their RISC-V processors, it clearly indicated their intent to target AI inference with hundreds or perhaps thousands of concurrent threads running in their advanced caching and pipelining scheme. Two recent announcements around Embedded World 2025 reinforce their… Read More
TRNG for Automotive achieves ISO 26262 and ISO/SAE 21434 compliance
The security of a device or system depends mainly on being unable to infer or guess an alphanumeric code needed to gain access to it or its data, be that a password or an encryption key. In automotive applications, the security requirement goes one step further – an attacker may not gain access per se, but if they can compromise vehicle… Read More
Webinar: RF design success hinges on enhanced models and accurate simulation
Traditional RF board design strategies based on circuit simulation worked at lower frequencies and relatively large spacing between components. Higher frequencies and densification dominate RF designs now, where corresponding wider bandwidths and tighter layouts with closely spaced components produce more complex 3D… Read More
Crosstalk, 2kAmp power delivery, PAM4, and LPDDR5 analysis at DesignCon
High-speed digital (HSD) designers have long tested the limits of realizable speed. GHz frequencies are now the norm, and multi-level signaling is pushing rates higher while the long-awaited transition to optical signaling and even higher rates looms ever closer. Power density is also climbing, and data-hungry applications… Read More
