Abstract

The MOSAIX is a wafer-scale, full-functionality prototype ASIC for the ALICE Inner Tracking System (ITS3) upgrade, implemented in 65 nm stitching technology. It integrates 144 independently powered pixel matrices, eight 10 Gb/s serializers, and on-chip data and power distribution, making full-chip verification highly resource-intensive (over 80 GB of memory and 192,000 tests). Verification also targets a sophisticated power-up sequence and radiation conditions of 106\ particles s−1 cm−2 and 4 kGy TID. This work presents a UVM-based verification strategy that identified 260 design errors and summarizes key lessons from ASIC sign-off.
