Description

Report the results of the specified AXI transactions on the JTAG to AXI Master, hw_axi.

You can use this command after creating hw_axi_txn objects on existing hw_axi objects, and then running the hw_axi to exercise the defined transaction.

The JTAG to AXI Master core can only be controlled using Tcl commands. You can issue AXI read and write transactions using the create_hw_axi_txns command. However, before issuing these commands, it is important to reset the JTAG to AXI Master core using the reset_hw_axi command.

This command reports the transaction data in the specified format, or returns an error if it fails.

Arguments

-w <arg> - (Optional) The number of data bytes per output line. The default is 8 bytes per line.

-t <arg> - (Optional) Specify the form and size of the output data. The accepted values for formatting the transaction data are:
  • d[SIZE] signed decimal, SIZE bytes per integer
  • b[SIZE] binary, SIZE bytes per integer
  • o[SIZE] octal, SIZE bytes per integer
  • u[SIZE] unsigned decimal, SIZE bytes per integer
  • x[SIZE] hexadecimal, SIZE bytes per integer
  • The default output format is x4, or 4-bytes in hex.
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
Note: Any errors encountered on the command-line, while launching the command, will be returned. Only errors occurring inside the command will be trapped.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
Note: Message limits can be defined with the set_msg_config command.

<hw_axi_txns> - (Required) The hw_axi_txn objects to report. The hw_axi_txn must be specified as an object returned by the get_hw_axi_txns command.

Example

This example resets the hw_axi core to a known state from which to begin running AXI transactions; then creates an AXI transaction associated with the hw_axi to read the contents of the first four locations of the AXI core; then runs the hw_axi to process the transactions associated with the core; and finally reports the data read from the transaction: 
reset_hw_axi [get_hw_axis hw_axi_1]
create_hw_axi_txn read_txn [get_hw_axis hw_axi_1] -type READ \
   -address 00000000 -size 32 -len 4 -cache 3 -id 0
run_hw_axi [get_hw_axi_txns [get_hw_axis]]
report_hw_axi_txn [get_hw_axi_txns read_txn]
This example creates AXI read and write transactions, runs the hw_axi, and reports on the results: 
create_hw_axi_txn wr_txn [lindex [get_hw_axis] 0] -address 80000000 \
-data {11112222 33334444 55556666 77778888} -len 4 -type write
create_hw_axi_txn rd_txn [lindex [get_hw_axis] 0] -address 80000000 \
-len 4 -type read
run_hw_axi [get_hw_axi_txns wr_txn]
set wr_report [report_hw_axi_txn wr_txn -w 32]
puts $wr_report
run_hw_axi [get_hw_axi_txns rd_txn]
set rd_report [report_hw_axi_txn rd_txn -w 32]
puts $rd_report
close_hw_target;
disconnect_hw_server;
