status - 2021.2 English

The status command reports the status of the Vitis performance monitor (SPM) and lightweight AXI protocol checker (LAPC) debug IPs contained in the xclbin programmed to the card.

xbutil status [-d <card>] [--debug_ip_name]

The following table lists the available options.

The status command displays the type and number of the debug IP on the accelerator card.

xbutil status

An example output of the command is shown below. It lists all the debug IP found.

INFO: Found total 1 card(s), 1 are usable
Number of IPs found: 9
IPs found [<ipname>(<count>)]: aim(5) tracefunnel(1) monitorfifolite(1) monitorfifofull(1) accelmonitor(1)
Run 'xbutil status' with option --<ipname> to get more information about the IP
INFO: xbutil status succeeded.

The list of available IP is determined by the xclbin file compiled for use on the accelerator card and include:

Accelerator Monitor (AM)

Count and trace the executions of compute units. Performance Monitors are added using the --profile.exec option as discussed in described in --profile Options.

AXI Interface Monitor (AIM)

Count and trace transactions on AXI4 connections.

AXI4-Stream Monitor (ASM)

Count and trace transactions on AXI4-Stream.

Lightweight AXI Protocol Monitor (LAPC)

Protocol checking of AXI4. Protocol checkers are added using the --debug.protocol option as described in --debug Options.

Streaming Protocol Checker (SPC)

Protocol checking of AXI4-Stream.

Trace Funnel

Collects trace events from all monitors. If present, then trace was enabled using the --profile.data option during compilation as described in --profile Options, and using the opencl_trace option during runtime as described in xrt.ini File.

FIFO Lite

Control of the PL FIFO that stores trace events. If present, then trace was enabled during compilation and runtime, and memory offload was specified to be a FIFO in the PL using the --trace_memory option during compilation as described in Vitis Compiler General Options. Trace behavior is influenced by the settings in the xrt.ini File.

FIFO Full

The data offload of the PL FIFO that stores trace events. If present, then trace was enabled during compilation and runtime, and memory offload was specified to be a FIFO in the PL using the --trace_memory option during compilation.

TS2MM

Takes trace events and offloads them to a memory resource (DDR, HBM, PLRAM). If present, then trace was enabled during compilation and runtime, and memory offload was specified to be a memory resource using the --trace_memory option during compilation as described in Vitis Compiler General Options.

You can get the status of specific IP using the following command syntax:

$ xbutil status --<ipname>

An example output using the --aim option is shown below:

$ xbutil status --aim

If no debug IPs are found in the xclbin, the following message is displayed below:

INFO: Found total 1 card(s), 1 are usable
INFO: Failed to find any debug IPs on the platform. Ensure that a valid bitstream with debug IPs (SPM, LAPC) is successfully downloaded. 
INFO: xbutil status succeeded.
