AR# 11788
4.2i Foundation - Advanced implementation options (such as a 5-input function) is not available in MAP Options when I target Virtex architecture
General Description: I am using Foundation Project Manager and targeting a Virtex (or Spartan-II) device. Many of the advanced implementation options are not available.
For example, in "Implementation Options", under "MAP", the option "Generate 5-Input Functions" is not available.
解决方案
Any option that is not available in the standard GUI can be set in the Template Manager or by using command line implementation.
(Please see (Xilinx Answer 6673) for instructions on using the Template Manager.)
The command lines for MAP to create 5- and 6-input functions are:
map [options] infile[.ngd] [pcf_file[.pcf]]
For 5- or 6-Input functions, please specify:
-k 5 or -k 6
The command will be: map -k 5 design.ngd design.pcf
