2015.x Vivado HLS ignores directives in a directives file when sourcing from the run_hls.tcl command. How do I source/import a directives file?

Description

2015.x Vivado HLS ignores directives in a directives file when sourcing from the run_hls.tcl command. 

How do I source a directives file?

Solution

In 2015.x there is a known issue where the importation of directives from a directives file being sourced inside another Tcl script will be ignored unless synthesis is run. 

In order to preserve the imported directives, ensure that the Tcl script sourcing the directives file contains the synthesis command csynth_design.
