Semiconductor firms report advancements in AI chip connectivity and testing

The semiconductor sector is seeing diverse developments across chip design, testing, and power management. Synopsys, Inc. has demonstrated a 3D PCIe 6.0 milestone using a stacked-die architecture. This design, which utilizes 5-nanometer technology and PAM4 signaling, aims to provide higher bandwidth and lower latency for AI accelerators, high-performance computing (HPC) systems, and data centers.

In the testing space, Teradyne, Inc. has received a rating upgrade to Buy. Analysts cite increasing demand for chip volume and complexity, driven by data center growth and AI, as key tailwinds for the company’s testing services.

Magnachip Semiconductor Corporation is currently undergoing a strategic transformation to become a pure-play power semiconductor provider. Under new leadership, the company is targeting higher-value silicon carbide (SiC) markets through a partnership with Navitas, though it continues to face challenges regarding revenue contraction and margins.
