"-opt_mode SPEED";                # Optimization Criteria # AREA or SPEED
"-opt_level 2";                   # Optimization Effort Criteria: 2=High
## "-shreg_min_size 3";           # not available for Spartan-3 !!
"-shreg_extract NO";              # --> switch shreg extraction off instead
"-uc <design>.xcf";               # Constraint File name
## Note:
##   "-use_new_parser yes";
## solves some nasty 'INTERNAL_ERROR:Xst:cmain.c:3464:1.56' problems, but
## leads to other problems later on (un-routable designs ect).
## Therefore currently not used.
