# Options for XST

#

#

#

Program xst

-ifn _xst.scr;            # input XST script file

-ofn _xst.log;            # output XST log file

-intstyle xflow;                  # Message Reporting Style: ise, xflow, or silent

#

# The options listed under ParamFile are the XST Properties that can be set by the

# user. To turn on an option, uncomment by removing the '#' in front of the switch.
