2008年8月5日 · lvcmos25 lvcmos33 group:comp.arch.fpga I implement a design in spartn3, and set the io standard to lvcoms33(or lvttl) but it always fails in mapping "ERROR ack:1655, the timing-driven phase encoutered an error". if I change the io standard to lvcmos25, then it pass. Dose anybody know what's the problem? Thanks in advance gauz
