Abstract The high-luminosity upgrade to the LHC (HL-LHC) requires an all new inner detector, the Inner Tracker (ITk), composed of strips and pixels subsystems. The AMACStar is one of three radiation hard ASICs that will be installed on the ITk strip modules. Its function is to autonomously monitor and control the temperatures, voltages, and currents in the module components, preventing these quantities from reaching dangerous levels. A total of 18000 AMACStars are needed for the detector requirements. Wafers of these chips are probed at the University of Pennsylvania; comprehensive probe-station testing software and procedures have been developed in order to test the digital and analog functionality of every AMACStar. A detailed grading scheme is applied to determine which chips should be installed on the modules. The results from the pre-production and production priming satisfy the required 90% yield needed for production goals. Production of AMACStar will begin in 2023.
