I tried both ISE/EDK 7.1 and 6.3 (all with latest service pack, bu tested very quicly), and I'm having some problems with 7.1. Fo example, a Microblaze design that fit in 6.3 doesn't fit as tight i
7.1. Moreover, I'm using Spartan-3 (FG456, speed: -4) with 66.6MH clock, and I can't meet the timing requirement in 7.1, while 6.3 mee it. Moreover, for the same design, 6.3 give 6 level of logic in th critical path, while 7.1 give 9 levelsAlso, with 7.1, when doing synthesis, I get a lot of warnings, lik
'Packer: ... can not be packed with the carry due to conflict ...'. Some other warnings too. With 6.3, no such warnings
I'm currently testing on a workstation with 6.3, and I'll verify i
some of the other issues I was having are there or not
Anyone having bad experience with 7.1
