Yes, back annotation would suit my needs well. For me the best solution would be to support underconstrained netlists; by this I mean a netlist where I can specify 8 data pins on a DRAM IC and specify that each of those pins needs to connect to one and only one of a set of (say) 10 pins on the FPGA. During manual routing selecting one of the DRAM data pins would highlight the 10 possible corresponding pins on the FPGA. I'd love to have this feature, but not enough to invest the time to code it up, so perhaps log it as a feature request for now :) Best regards, Stephen
