The SignalTap Embedded Logic analyzer megafunction captures signals from anyinternal node or I/O pin of an APEX II or APEX 20K device in real-time atsystem speed. SignalTap analysis also works with all existing EDA synthesis tool design flows. SignalTap analysis also eliminates the need for external probes and design file changes to capture signals from an internal node. The logic analyzer controls and signal capture display are all accessible from the Quartus II design software. The MasterBlaster TM or ByteBlasterMV TM communications cables support data transfer between the APEX II or APEX 20K device and the Quartus II software for waveform display of signals captured by SignalTap logic analysis.……
