Testing

FONT SIZE : AAA

For a programmable device, you simply program the device and  immediately have your prototypes. You then have the responsibility to place  these prototypes in your system and determine that the entire system actually  works correctly. If you have followed the procedure up to this point, chances  are very good that your system will perform correctly with only minor  problems. These problems can often be worked around by modifying the system  or changing the system software. These problems need to be tested and  documented so that they can be fixed on the next revision of the chip. System  integration and system testing is necessary at this point to insure that all parts  of the system work correctly together.

When the chips are put into production, it is necessary to have some sort  of burn-in test of your system that continually tests your system over some long  amount of time. If a chip has been designed correctly, it will only fail because  of electrical or mechanical problems that will usually show up with this kind of  stress testing.
