Anotace:

Subject is focused on the test and measurement methods in digital technology. Standard instruments for digital device testing are described together with methods of their use. Basics of transmission theory, reflectometry and metastability are introduced. Next part is focused on measurement on computer buses, interfaces and serial communication channels and on methods of software and SW/HW interaction analysis. The "boundary scan? technology for digital circuits testing is introduced as well as methods for FPGA based implementations testing. Finally the mass production testing methods are introduced.
