The IEEE Latin-American Test Symposium (LATS, previously Latin-American Test Workshop - LATW) is a recognized forum for test and fault tolerance professionals and technologists from all over the world, in particular from Latin America, to present and discuss various aspects of system, board, and component testing and fault-tolerance with design, manufacturing and field considerations in mind. Presented papers are also published in the IEEE Xplore Digital Library. The best papers of the 18th LATS will be invited to re-submit to IEEE Design and Test of Computers, Journal of Electronic Testing: Theory and Applications - JETTA (Springer), Journal of Low Power Electronics - JOLPE (American Scientific Publishers), and IEEE Transactions on Computer-Aided Design (TCAD).
