Cover Story: PCB Routers Cut Time and Copper

November 19, 2008 9:12 am | by Jon Titus, Senior Technical Editor | Articles | Comments

At 3:00 PM on a Friday afternoon you devise a new design for a low-noise amplifier you've worked on for months. You want to try the circuit right away, but a quick-turn printed-circuit board (PCB) house cannot deliver boards until next week. You know another engineering group uses a PCB router to produce prototype boards in about an hour, so you decide to try it.

Embedded Systems: C and C++ Tools Reduce Code Errors

November 19, 2008 8:44 am | by Jon Titus, Senior Technical Editor | Articles | Comments

Programmers now have many tools that help reduce or eliminate problems. Unfortunately, they might not know these tools exist. "In 1998, the UK's Motor Industry Software Reliability Association (MISRA) published their standard for the C language to promote 'safe C' in the UK automotive industry," explained Chris Tapp, a field-applications engineer at LDRA. "The software industry has seen MISRA-C as a way to encourage good programming practice, focus on coding rules, and ensure well designed and tested safe code."
