In our example we will demonstrate how to test a specific UUT using the DIO board and creating and editing a vector file using DIOEasy.
The example UUT (figure below) is a circuit board that contains an 8-bit DAC and a local bus controller (LBC). The local bus controller connects to a larger distributed bus system.
GX5150 and UUT
A Master Controller Unit (MCU, not shown) coordinates all bus access by granting bus access to an LBC specified by an 8-bit address on the Address Line. The LBC, in turn, grants access to the DIO. When the LBC is finished using the bus, it relinquishes control to the MCU.
The LBC uses the Status and Control Bus to report back to the MCU.
