Simulated verification of the ASIC functionality and radiation tolerance for the HL-LHC ATLAS ITk Strip Detector

ASICs are important components in many HEP detectors and their functional simulation ensures successful operation while minimizing the number of long production cycles. Three radiation-tolerant ASICs (HCC, AMAC, and ABC) will perform the front-end readout, monitoring, and control of the outer layers of the ITk Strip particle tracker for the HL-LHC ATLAS detector. Simulated verification with the python-based cocotb framework allows for sophisticated tests with major contributions from students and firmware non-experts. The verification program includes interactions between multiple ASICs, realistic HL-LHC data flows, operational stress tests, and a focus on mitigation of disruptive Single Event Effects due to radiation.
