In-Circuit Debugger for Wireless Real-Time Monitoring and Diagnosis of FPGA Applications.

As the level of System-on-Chip (SoC) based embedded systems complexity continues to enlarge, the post-silicon validation stage contributes a major part of the entire development cost. Due to precipitous design complexity, it is nearly unattainable to detect and fix all design errors during the design phase. This paper presents a solution to resolve this problem with the help of a novel In-Circuit Debugger (ICD), which aims to enhance the post-production validation process by enabling observation and control of internal signals, such as input and output signals of safety critical systems. The ICD is an efficient technique for monitoring and verification of on-chip IP-cores. This paper proposes a novel system debugging technique and explains how it differs from existing techniques. Moreover, various use cases of ICD are also discussed in detail.
