The QDRII Tab
The QDRII tab allows you to independently test the QDR II interface on your board.
Figure 6–8 shows the QDRII tab. Since there are four QDR II ports on the Stratix IV
GT 100G board, the QDRII tab has 4 radio buttons to monitor each QDR II interface.
The following sections describe the controls on the QDRII tab.
Port
This control directs communications to one of four QDR II memory ports on the
board. Each interface is 18 bits wide.
Start
The Start control initiates QDR II memory transaction performance analysis.
Stop
The Stop control terminates transaction performance analysis.
