I just upgraded to ISE 7.1.03i. My old 6.3i design used some DCMs in a "not so legal" fashion, where I had CLKFX_DIVIDE = 33, and CLKFX_MULTIPLY =
- My old version of ISE (6.3i) would actually accept the divide value and produce a working bit stream. 7.1 on the other hand actually complains during the mapping phase. Is there a way to disable the checking of this and force it to accept those values?
Thanks,
