Part two explains the workings of the JTAG (IEEE 1149.1) boundary-scan technology. In software development, perhaps the most critical, yet least predictable stage in the process is debugging. Many ...

Troubleshooting communications test systems can be made easier if the hardware and software development are separated from each other. Problems can be more readily found and corrected by following ...

Back in the day, we'd write some code, compile, execute, see what happened and repeat. That was testing. (Sometimes that's still what testing looks like, for better or worse.) Today, we can do a lot ...

Modern multithreaded, asynchronous code can be hard to debug. The complexity that comes with message passing and thread management results in bugs that can seem non-determinant, with little or no way ...

Debugging embedded designs is becoming increasingly difficult as the number of observed and possible interactions between hardware and software continue to grow, and as more features are crammed into ...

The tips and tricks when testing motor-driver ICs on the lab bench can help engineers reduce time spent on evaluating and prototyping motor systems. The first installment of this two-part article ...

In increasingly complex SoC designs, many of which contain multiple cores and multiple modes, determining best practices for testing and debugging is a moving target. Jason Andrews, architect at ...

People have marketed the promise of AI and software development as a way to increase speed. Despite the benefits of auto-complete tools, someone still has to fix what breaks. Debugging drains hours ...
