Why Flexlets

As monolithic SoC designs approach physical and economic limits--reticle size constraints, yield challenges, and thermal bottlenecks--the semiconductor industry is shifting toward chiplet-based architectures. The Flexlets family from Socionext represents a breakthrough in this evolution: a new class of configurable chiplets designed to unlock the full potential of modular design.

Traditional chiplet solutions often rely on fixed-function ASSPs, limiting flexibility and customization. Flexlets change the game by offering a configurable RTL-level chiplet library, enabling customers to tailor performance to their unique application needs whether in high-performance computing, advanced networking, or next-generation automotive systems.

What are Flexlets

Flexlets are RTL-composable chiplets that give customers the freedom to integrate their own custom logic and select best-in-class IP from any vendor. Designed to shorten design cycles and accelerate time-to-revenue, Flexlets combine configurability with high performance across a wide range of applications.

The Flexlets Advantage

Socionext is launching a portfolio of flexlets, each integrating security, debug features, and optimized interfaces. Engineering samples, including Known Good Die (KGD), are in development. Availability details will be announced soon
