I also get an error at Section 4.4 of Workflow Advisor (Matlab R2015b, Vivado 2015.3).
Matlab generates the 'vivado_download.tcl' script with the following command:
connect_hw_server -host localhost -port 60001
but these arguments are deprecated in the Vivado 2015.3
the current syntax would be, according to Vivado help:
connect_hw_server [-url < arg >]
