Routing signals in priority

Hi, do you know if it's possible to force the router tool to route specified signals first. Thank you Arnaud

these signals are quite critical. I assign a MAX_DELAY constaints of 1ns. The router can't achieve it.

i'm quite sure that it can achieve it, because it achieve constraints in a previous routing (design was closed). that's why I want to force the routing of these signals first.

I create the .rcf file. I found signals, I remove others. And do I just to run a compilation? And tools keeps the selected signals? So I have to take the rcf from a design which was correctly routed?
