Hi Goran

CFG_DDR_CK_CYCLE = 20 in the mimas_v2 build. If you run a build you can 
see the values of these CFG_ and CONFIG_ values in the output 
directory's config sub-directory. You can build just the config files if 
you want too like this

$ make mimas_v2 TARGET=config/config.vhd
$ cat last_output/config/config.vhd
-- This file is generated by the makefile
package config is
  constant CFG_CLK_BITLINK_PERIOD_NS : integer := 8;
   constant CFG_CLK_CPU_DIVIDE : integer := 20;
   constant CFG_CLK_CPU_PERIOD_NS : integer := 20;
   constant CFG_CLK_MEM_2X_DIVIDE : integer := 10;
   constant CFG_CLK_MEM_PERIOD_NS : integer := 20;
   constant CFG_DDRDQ_WIDTH : integer := 16;
   constant CFG_DDR_CK_CYCLE : integer := 20;
   constant CFG_DDR_READ_SAMPLE_TM : integer := 2;
   constant CFG_SA_WIDTH : integer := 13;

end;
