Abstract
One example includes a test system that includes a printed circuit board and a switching interposer board. The switching interposer board is comprised of a probe point, a first bus, a second bus, and a set of switches. Each switch includes a first terminal, a second terminal, and a third terminal, the first terminal being coupled to a respective pin of an integrated circuit device, the second terminal being coupled to the first bus, and the third terminal being coupled to the second bus. Each of the set of switches have a first state that selectively couples a pair of the pins of the integrated circuit device to each other through the first bus during a short test, and a second state that selectively couples at least one of the pins of the integrated circuit device to the probe point through the second bus during a voltage level spike test.
