The Nexus-based trace implementation allows ongoing monitoring and recording of processor instruction execution.
Developers can use SEGGER’s J-Link PLUS, PRO and ULTRA debug probe options, as well as its Ozone debugger and performance analysis software package to take advantage of SiFive Insight using on-chip trace functionality. SEGGER debug probes also feature a backtracing capability (where the full execution history can be easily accessed and stepped through backwards).
Advanced features, such as code coverage and profiling, can also be used – based on the execution counters processed by the J-Link software. The Ozone debug software package can subsequently generate detailed code coverage reports for software validation purposes.
