Patent ID: 8516176

Claim:
A method comprising: receiving, by a first TAP controller of an IEEE 1149.X compliant master device, a first data; programming the master device with the first data; generating a second data subsequent to the programming of the master device with the first data; transmitting the second data to a first logic circuit and a second logic circuit; receiving, by a second TAP controller of a first IEEE 1149.X compliant slave device, the first data; programming the first slave device with the first data; generating a third data subsequent to the programming of the first slave device with the first data; transmitting the third data to the first logic circuit; receiving, by a third TAP controller of a second IEEE 1149.X compliant slave device, the first data; programming the second slave device with the first data; generating a fourth data subsequent to the programming of the second slave device with the first data; transmitting the fourth data to the second logic circuit; comparing, by the first logic circuit, the second data to the third data; signaling the result of the step of comparing the second data to the third data; comparing, by the second logic circuit, the second data to the fourth data; and signaling the result of the step of comparing the second data to the fourth data.
