While superior-quality functional board test has been a goal for most high
reliability electronics manufacturers, the time and effort For generating s
uch test programs using today's tools and processes makes this difficult to
achieve in a cost effective manner. This paper will introduce a revolution
ary approach to functional board test program development that combines the
comprehensiveness of software-based simulation with the speed and simplici
ty of hardware emulation. The result is a functional Test Program Set devel
opment system that can produce high fault coverage, diagnostic test program
s in a fraction of the time it takes using traditional techniques, and at a
lower unit cost.
In this paper we will first provide a brief background on the strengths and
weaknesses of current software and hardware TPS development techniques-sim
ulation hot mock-up. Next, the new approach will be described in detail and
contrasted against the existing techniques. Finally, we will present actua
l experience to date using a prototyped system.
