Abstract
To improve testability of analog or mixed analog/digital circuit modules mounted on a carrier, three-way switches are placed at input and output ports of the circuit modules. The switches can operate to establish signal connections between a test bus and core circuits inside the modules. The switches can also establish signal connections between the test bus and glue circuits disposed between the modules.
