Diagnostic Test Details
3.3.1
User I/O & Nios Features Test
The User I/O and Nios® features of the Stratix® II Memory Board 2 are tested using a
Nios II-based system controlled by a host computer. The host computer runs the board
test system (BTS), and the tool command language (TCL)-based application using the
Quartus® II TCL application program interface (API). The BTS host application uses an
RS-232 cable connected to the Stratix II Memory Board 2 to communicate with the Nios
system.
