Leave the wires to last-functional evaluation of the IEEE Std 1149.5 module test and maintenance bus
Rodham E. Tulloss · 2002
The IEEE Std 1149.5 Module Test and Maintenance (MTM) Bus Standard is described using a high level model of system testing. Constituent elements of the Standard are examined as logical consequences of and choices based upon, this model. Functionality of the bus is outlined; and its cost of implementation, discussed. The MTM-Bus is briefly compared to IEEE Std 1149.1 with regard to the number of conformant devices necessary in order for the MTM-Bus to be usable. Standardized support of "live insertion" of modules is presented as an example of non-test application of the MTM-Bus. Current status of IEEE Std 1149.5 is provided.
