Categories
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.
-verbose
- (Optional) Temporarily override any message limits and return all messages from this command.
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.
