Hi All, I am working with a micro-processor conneted to 8 SDRAM with 12 address lines to all SDRAMs and 32 data lines each to two sets of four SDRAMs. I was wondering if anyone has managed to route this sort of topology without using terminations. If so please send information on topology used. The IO are lvttl compatible at 3.3V. Any input on routing possibilities is welcome. Thanks & Regards, Alex. --------------------------------- Yahoo!
