Multi-die Testing In The Field Must Build On Established Test Methodologies

As semiconductor technology advances toward more advanced nodes, testing challenges for multi-chip systems (MCS) are becoming increasingly complex. In mission-critical applications such as data center... Read original →

The evolution of in-field multi-die testing is forcing EDA toolchains and advanced packaging processes into tighter integration. Siemens EDA and Synopsys must unify embedded deterministic test (EDT) flows with on-chip monitor telemetry to enable closed-loop silicon lifecycle management. Meanwhile, TSMC’s (China Taiwan) high-density microbump interconnects in 2.5D/3D-IC stacks are making sacrificial pads a non-negotiable redundancy for yield assurance. This shift raises compliance barriers: ISO 26262 and JEDEC standards will soon mandate real-time aging analytics, disproportionately burdening smaller chipmakers. In response to proteanTecs’ vertical predictive-analytics play, established EDA vendors may accelerate acquisitions to embed live diagnostics. Within 18 months, repurposing PCIe/USB as test interfaces will become standard—but bandwidth constraints could ignite a new IP arms race around dedicated test fabrics.
