Description
Run the AXI transactions defined on the specified JTAG to AXI Master core.
AXI transactions are created with the create_hw_axi_txns command.
Run the specified hardware AXI read/write transactions on the AXI bus, and update the transaction status on the associated hw_axi object.
Arguments
-queue - (Optional) Run the specified hw_axi transactions in queue mode. Queued operation allows up to 16 read and 16 write transactions to be queued in the JTAG to AXI Master FIFO and issued back-to-back for low latency and higher performance between the transactions. Non-queued transactions are simply run as submitted.
-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) Specify the hardware AXI Transaction objects to run on the AXI bus. The objects can be returned by the get_hw_axi_txns command.
