The growing complexity of modern chips has caused an increasing share of the verification effort to shift towards post-silicon validation. This phase is challenged by poor observability, limited off-chip bandwidth, and complex, concurrent communication interfaces. Furthermore, pre-silicon verification and post-silicon validation methodologies are very different and share little information between...
This paper presents a proposal of debugging enhancements embedded in Network-on-Chip. Such approach makes debugging functionality hardly attainable in classical hardware methodology. We introduce real-time packet sniffing and monitoring with the use of multicast transmission. Each packet in the debug mode is additionally sent to an off-chip control device, called Off-chip Debugging Host (ODH), as...
Call traces expose runtime behaviors that greatly aid system developers in profiling performance and diagnosing problems within wireless embedded applications. Strict resource constraints limit the volume of trace data that can be handled on embedded devices, especially bandwidth limited wireless embedded systems. We propose two new call trace gathering techniques, local identifier logging and control...
