Democratizing Chiplet Connectivity.

CircuitPath is the open-source integration layer within Conduit Systems, focused on solving one of the most critical challenges in modern computing: how chiplets—memory, compute, and accelerators—are physically and logically connected. As workloads scale and architectures shift away from monolithic designs, performance is increasingly determined by the efficiency of interconnects and packaging. CircuitPath addresses this by providing a standardized, simulation-driven framework for advanced packaging, enabling developers to design and optimize multi-die systems with precision before any hardware is built.

At its core, CircuitPath introduces a modular approach to chiplet connectivity built around real-world technologies such as UCIe-style die-to-die links, 2.5D interposer architectures, and emerging 3D stacking techniques. It includes reference layouts, parametric interposer generation, and thermal-aware floorplanning, allowing users to model bandwidth, latency, signal integrity, and power distribution across complex systems. Rather than treating packaging as a static constraint, CircuitPath elevates it into a programmable layer—one that can be tuned and optimized alongside compute and memory.

One of its most innovative updates is the emphasis on simulation-first development. CircuitPath provides a digital twin of the packaging layer, enabling engineers to test system configurations, predict bottlenecks, and refine designs before fabrication. This dramatically reduces cost and iteration time while improving system reliability. Additionally, its extensible ecosystem allows contributors to introduce new chiplet models, interposer designs, and routing strategies, ensuring that the framework evolves alongside advancements in semiconductor technology.

By making advanced packaging open and accessible under an AGPL-3.0+ license, CircuitPath lowers the barrier to entry for startups, researchers, and independent developers who would otherwise be locked out of high-performance hardware design. It transforms chiplet connectivity from a proprietary advantage into a shared foundation, accelerating innovation across AI and high-performance computing.
