2016.1 Vivado - Tcl regular expression syntax for filter function changed to BOOST


In Vivado 2016.1 the regular expression syntax for the filter command has changed.  This is also the case for all commands using the filter command as an option (-filter).

When -regexp is specified, the BOOST syntax is now used, not the regular Tcl regexp syntax described in re_syntax help, and mentioned in (UG835) v2016.1, April 6, 2016.


BOOST syntax is also used in Perl.


For all filter calls with -regexp, use BOOST syntax.

For all other regular expression commands, use the Tcl re_syntax.
