Mig 3.1 Fmax or Fspecific?

I'm using ISE 11.1 with MIG 3.1.  If I generate a MIG core for Virtex-5, without a PLL at, say 266 MHz, do I need to generate another core to run at, say 133 Mhz?  Or can I just adjust my PLL accordingly?

You need to make sure to adjust all the related parameters (e.g. CLK_PERIOD) in addition to changing the PLL.

It's easiest to rerun MIG as you do need to make sure that all the parameters are correct for the specific frequency.
