Ever wanted to see a good animated presentation on functional testing and debugging on prototype boards and digital embedded systems? Well, here is your chance.
Nowadays circuits use digital interfaces that may run at more than a few 10th of megahertz. The old way to do it with micro-controllers coupled with a GPIO is not practicable any more. By substituting for missing pieces and offering maximal flexibility when generating digital logic signals, digital pattern generators have become a valid and strong alternative.
This presentation shows why generating digital input is key to successful testing and debugging of embedded systems.
To emulate missing parts of an embedded system with a digital pattern generator is a great thing. Not only to ‘fill the slot’, but rather to be able to control the digital stimulus source with ease of use and all the debug functionality that goes with it.
Read a survey on using hardware prototypes to speed up embedded system debug and learn how to substitute the digital pattern generator system for components that are not available yet.
A logic analyzer is commonly used for debugging embedded systems but is it really the right tool for this purpose? What if I’m not seeing all the data? Click through this interactive presentation below and you’ll find some interesting things…
Digital input stimulus generation is system analysis’ counterpart. When going to ‘real hardware’ prototype early in the design cycle of your embedded system, a digital stimulus source allows emulating the missing parts of your embedded system.
What is a digital pattern generator?
A digital pattern generator is an essential stimulus source for almost every type of digital device: digital and mixed-signal ASIC, FPGA, microprocessors and microcontrollers. The digital pattern generator can be used early in the design cycle to substitute for system components that are not yet available.
Because nowadays circuits use digital interfaces that may run at more than a few 10th of megahertz, the old way to do it with microcontrollers coupled with a GPIO is not practicable any more. By substituting for missing pieces and offering maximal flexibility when generating digital logic signals, digital pattern generators speed up new product’s time-to-market.
The digital pattern generator is an effective solution just about anywhere that complex digital bit streams are needed to stimulate a device under test (DUT).
