DFT basics

DFT stands for Design For Testification. DFT engineers try to make the testing of design more cost effective by introducing some structures into the design itself. By doing so, the overall test cost, and hence, cost of production comes down. Below, we list some of our posts covering the basics of DFT. Please provide your feedbacks regarding the topics you want to see as a part of this list. :-) Happy learning.
