Is it possible to write s/w for h/w testing?
Can we also find out exact fault location? Sure you can - and the principle is exactly the same as if you did it manually; ie, Obviously, the software requires supporting hardware; Loopbacks are often useful here. Memory check can be done by writting random data at random location and reading back from same location. Probably not very effective. For a detailed description of the failure mechanisms in memory systems, and how to test them thoroughly & effectively, see: http://www.netrino.com/Articles/MemoryTesting/ Also search here for the many previous discussions of memory testing!
