Trace Accelerates Debug Analysis in Complex Linux Systems

Step-by-step approach reveals root causes in unexpected places

Software engineers can spend days or weeks tracking down bugs in complex software for multicore systems-on-a-chip (SoC), often delaying new product introductions. A new eBook by ASSET® InterTech explains how developers can take advantage of both trace and static analysis tools for greater insight into code execution and to identify root causes faster. The eBook describes a real world case study involving a SoC with Linux, but the methodology could be applied to software for Intel multicore processors as well.

ASSET® InterTech (www.asset-intertech.com), a leading supplier of software and hardware debug, validation and test tools.

“The problem is usually these bugs manifest themselves in one place in the code, but the real root cause is somewhere totally different, quite possibly in a process running on a different core entirely,” said Larry Osborn, an ASSET senior product manager and author of  the new eBook. “As a result, applying multiple tools – both trace and static analysis – is the best way to get the visibility that the engineer needs. This case study looks over an engineer’s shoulder, if you will, and outlines a step-by-step approach to trace back to the real root cause in a fraction of the time.”

Titled “Trace Accelerates Debug Analysis in Complex Linux Systems,” the new eBook shows how the root cause of a core dump bug was quickly found in code running on another core. The eBook is free and available for downloading now from the ASSET InterTech website in the eResources center.
