Tool reusable for DSP system emulation and board production testing
David Ruimy Gonzales · 2002
Tools that support designs that use the IEEE 1149.1 JTAG port for emulation and board test are becoming more common. These tools not only are used to debug hardware and software interaction but are now used to validate the design using sophisticated board test techniques. High level languages are now being used to describe these designs and the complex interaction of boundary scan cells and built in self-test circuits. These tools provide the necessary set of capabilities for getting the job done quickly at all levels of the product life cycle. The use of a 60MHz DSP56002 as a JTAG controller allows developers to utilize a common tool on various computer platforms using a Motorola GUI or developing their own custom built utilities using a set of readily available device drivers and libraries. The three newest Motorola DSP core based architectures (DSP56300, DSP56600 and DSP56800) have IEEE 1149.1 JTAG ports for emulation and pin boundary scan. Development tools which support full source code emulation in the target system as well as board/system level boundary scan cell control are available for these cores.
