We present a novel debug approach which offers visualization of hardware/software interaction for system level verification. The debug concept comprises debug probes within each
In addition to independent control over processors, it is vital that the comprehensive debug environment also support synchronous operation of some or all of the processing cores.
We proposed ManyGUI, a graphical tool to debug many-cores, composed of a data extraction and classification framework connected to a set of graphical frames that allows to represent the many
An example FPGA design, targeted for a Microsemi SmartFusion2 SoC FPGA device, can be used to demonstrate some of the advantages and disadvantages of these standard techniques as well as the
To switch the context to another core, simply highlight the stack frame for that other core in the Debug view and the various views will be updated to reflect the context of that core. Most debugging views,
In this paper, the dynamic tracing infrastructure of GNU debugger (GDB) was investigated to understand its performance limitations. Thereafter, we propose an improved architecture for
Effective debugging in large-scale applications demands a structured approach, robust observability, and collaborative culture. As systems become more distributed and complex, it is vital for
This worked well for single-core systems, but with the growing portfolio of multi-core SoCs (like the heterogeneous 64-bit 5-core RISC‑V U-540 core complex found in
Recent work has provided a perspective on this issue for mes- sage passing parallel programs.1In further considering large software frameworks, we need steady progress in systematic testing
6.1 Introduction The major challenge verifying, debugging and profiling applications on many-core processors comes from the non-intuitive nature of the program flow: in fact, there are at
The paper is organized as follows: the following section describes related work on NoC debugging techniques, extending the number of debug interfaces, and a multi-core hardware architecture which
Debug support is based on two components: OCDS (On-Chip Debug System) and MCDS (Multi Core Debug Solution), which offer debugging and performance optimization for the software and system
This guide shows you practical techniques to debug massive parallel applications across thousands of cores without bringing your entire computation to a standstill.
For multi-core timing related issues that occur only sporadically, manual debugging is very time-consuming or sometimes even impossible. Therefore, a novel automated system diagnosis and
Configuring a debugger to work with a core in a multi-core environment does not require special settings. All that is required is proper setup of the scan chain for each debugger. This enables SAM
Debugging—the process of identifying, localizing and fixing bugs—is a key activity in software development . Due to issues such as non-determinism and difficulties of reproducing
