This section describes the transaction viewing features specific to AXI-Stream protocol instances. A protocol instance of an AXI-S interface appears in the wave window with a wave object hierarchy as shown in the following figure.
The wave object hierarchy of an AXI-S interface contains only one transaction row which is at the top of the hierarchy. Each transaction bar in the row corresponds to one complete AXI transaction. The text on the transaction consists of the stream identifier from AXI signal TID and the coarse routing information from AXI signal
The transaction bar contains color coded stripes to indicate the status of an AXI transaction as described in the following table.
|Green||Normal||Data is streaming normally.|
|Yellow||Starve||Slave is waiting for data from the master.|
|Red||Stall||Master is producing data faster than slave can consume it.|
Under the top transaction row, the wave object hierarchy contains some of the key AXI signals plus
starve status signals to indicate stall and starve conditions. The status signals provide the same information as the color stripes do in the transaction row.
A handshaking error produces an error transaction with the text containing all Fs.
