Honored ContributorHi Mariam,
Altera devices do not have perfectly regular routing, so it would be very difficult to reproduce exactly the same routing in one part of the chip in another part. This is in addition to the fact that some columns have MLABs, MACs or RAMs instead of normal logic, so if any components are duplicated side-by-side, they may not even be able to reuse the same placement, let alone routing. Why do you need the routing to be identical? The standard way to work is to set the same timing constraints (using SDC files) on the different components so that they're all optimized to the same extent. Cheers, Adrian Ludwin Altera Corp
