ALTERA CORPORATION INTRODUCTION TO QUARTUS II ■ 197
Figure 2. SignalProbe Debugging Flow
Using the SignalTap II Logic
Analyzer
The SignalTap II Logic Analyzer is a second-generation system-level
debugging tool that captures and displays real-time signal behavior,
allowing you to observe interactions between hardware and software in
system designs. The Quartus II software allows you to select the signals to
capture, when signal capture starts, and how many data samples to capture.
You can also select whether the data is routed from the device’s memory
blocks to the SignalTap II Logic Analyzer via the JTAG port, or to the I/O
pins for use by an external logic analyzer or oscilloscope.
You can use a MasterBlaster
™
, ByteBlasterMV
™
, ByteBlaster
™
II,
USB-Blaster
™
, or EthernetBlaster communications cable to download
configuration data to the device. These cables are also used to upload
captured signal data from the device’s RAM resources to the Quartus II
software. The Quartus II software then displays data acquired by the
SignalTap II Logic Analyzer as waveforms.
