Hi all, i am designing a circuit for a cryptogrpahy application based on elliptic curve cryptography.I want to know one thing when i implement the same circuit on different devices from different families results are as follows. with spartant3 i m getting max. frequency as 89 Mhz with virtex2 i am geting max. frequency as 123 MHz but to my surprise with vortex-e-2000 i am getting max. frequency as
48MHz. can anyone explain why performance of virtex-e-2000 is like this.thanks.
