Vivado - report_environment is taking a long time to run; stalls during "Fetching license information"


I am running the report_environment command and it takes a long time to complete.

It gets to the "Fetching license information" stage and then seems to stall.

Vivado% report_environment
INFO: [Common 17-635] Now fetching report information.  This may take some time.
INFO: [Common 17-633]   Fetching system information...
INFO: [Common 17-632]   Fetching software environment information...
INFO: [Common 17-629]   Fetching Vivado preferences...
INFO: [Common 17-630]   Fetching installation information...
INFO: [Common 17-628]   Fetching DLL information...
INFO: [Common 17-631]   Fetching license information...

Is there anything that can be done to speed up the command?


The report_environment command relies on a licensing API to gather the license information. 

The speed of gathering the license information will depend on the speed of the license check and the number of paths and files that are searched. 

The search time increases significantly when multiple network and floating license servers are in the license path.

The time to run the report_environment command can be reduced in the following ways:

  • Remove any un-needed license files or licenses from the search path; see (Xilinx Answer 33026).
  • If license information is not required in the report, use the following Tcl set_param to avoid the license check:
set_param report_environment.getLicenseData false
