You're better off to start with a new design, and then if you get stuck with it, post it and a simulation here, or file a Service Request with Altera. --- Quote Start --- Perhaps there is a needle-in-a-haystack fitter or synth setting to resolve. --- Quote End --- I have yet to find the "fix this poor example" button :) Cheers, Dave
