Professor Kevin Warren of Vanderbilt University delivered this lecture for the Introduction to Radiation Effects Engineering online SCALE course.
Designing electronic systems that must operate reliably in radiation‑rich environments is a critical challenge for space, defense, and high‑energy physics applications. The resource addresses the full spectrum of circuit creation, from device‑level physics to board‑level integration, emphasizing why radiation tolerance is essential for mission‑critical hardware. It situates the topic within modern engineering practice, where failure mechanisms such as single‑event upsets and total ionizing dose must be anticipated early in the development flow.
The presentation details a hierarchical methodology that begins with silicon‑level verification, employing TCAD simulations to predict device behavior before fabrication. At the integrated‑circuit level, designers extract GDSII layout data, construct three‑dimensional solid models, and import them into the Monte‑Carlo Radiation Effects Designer (MRED) to transport heavy ions, protons, neutrons, and photons through the geometry. A Python‑based glue layer converts the resulting charge‑deposition information into radiation‑enabled netlists, which are then executed in conventional circuit simulators; the workflow iterates until statistically robust failure statistics are obtained. The discussion also compares commercial radiation‑analysis tools, highlighting differences in fidelity, user interface, and visualization capabilities.
With this knowledge, learners can articulate the hierarchical approach to circuit design and verification for radiation environments and critically evaluate the capabilities of various analysis tools. They acquire the ability to engineer layout strategies that minimize susceptibility to radiation‑induced failures, interpret simulation data to pinpoint vulnerable transistors, and apply a Python‑driven workflow that seamlessly integrates radiation effects into circuit simulations. These competencies enable informed design decisions for robust, radiation‑hardened electronic systems.
