This page hosts our HLS In-System Debugging framework. This work has been described in several publications:
- Effective FPGA debug for high-level synthesis generated circuits (FPL 2014)
- Using Dynamic Signal-Tracing to Debug Compiler-Optimized HLS Circuits on FPGAs (FCCM 2015)
- Allowing Software Developers to Debug HLS Hardware (FSP 2015)
- Using Round-Robin Tracepoints to Debug Multithreaded HLS circuits on FPGAs (FPT 2015)
- Quantifying observability for in-system debug of high-level synthesis circuits (FPL 2016)
- Signal-Tracing Techniques for In-System FPGA Debugging of High-Level Synthesis Circuits (TCAD 2017)
- Enabling Long Debug Traces of HLS Circuits Using Bandwidth-Limited Off-Chip Storage Devices (FCCM 2017)
