In the User guide it is said that the DDR2 micron component is running in 133mhz, but opening edk project I see that the signal DDR2_SDRAM_MPMC_CLK_S is actually a 125mhz clock
1. If i am using mig for that device, should i choose 125mhz frequency and bot 133 because i cannot produce a 133mhz clock from my dcm?
2. If i want to choose anothe ddr2 component, for example a ddr2-667 (333mhz) will i still be able to operate it with MIG, at the maximux frequency the spartan can work with? (166mhz)
