Title: Craig A Chancellor: Innovator in Fault Insertion Technology

Introduction

Craig A Chancellor is a notable inventor based in Upton, MA (US). He has made significant contributions to the field of fault insertion technology, particularly in integrated circuits. His innovative work has led to the development of a patent that addresses critical issues in fault detection and recovery systems.

Latest Patents

Craig A Chancellor holds a patent for "Transient and intermittent fault insertion." This patent describes fault insertion circuits under programmable control that reside in an integrated circuit (LSI or VLSI). These circuits are designed to insert transient and intermittent fault classes, in addition to a permanent fault class, into functional logic on such integrated circuits. The specific fault types that can be programmed for each fault class include a stuck-open fault and bridging faults, both wired-AND and wired-OR. The programmable fault insertion circuitry interfaces directly or indirectly with a Built-In Test (BIT) maintenance controller. This technology not only verifies test software but also enhances the verification of a fault-tolerant system's error detection and recovery circuits through fault insertion testing.
