# Test against Xilinx Spartan 3A and ISE.
#
# To replicate the performance runs:
# - Minimum resource utilization, use -5 speed grade, 15 ns clock, XST and MAP
#   set for minimum area.  ISE 11.4, 12.4, 13.3, and 14.4 gave identical
#   results:  130 slices, 231 LUTs
# - Maximum speed
#   -4 11.4 8.1 ns "-timing -t  57" ==> 8.102 ns (123.4 MHz)
#   -4 12.4 8.2 ns "-timing -t  25" ==> 8.165 ns (122.5 MHz)
#   -4 13.3 8.0 ns "-timing -t  84" ==> 8.074 ns (123.3 MHz)
#   -4 14.4 8.1 ns "-timing -t  22" ==> 8.127 ns (123.0 MHz)
#   -5 11.4 6.7 ns "-timing -t  83" ==> 6.757 ns (148.0 MHz)
#   -5 12.4 6.8 ns "-timing -t  24" ==> 6.771 ns (147.7 MHz)
#   -5 13.3 6.7 ns "-timing -t  53" ==> 6.744 ns (148.3 MHz)
#   -5 14.4 6.8 ns "-timing -t  31" ==> 6.773 ns (147.6 MHz)
