What is "strange" is that the design was working when it was not very crowded. More precisely, with a half-filled design, I see "2.045ns physical path delay" instead of 0.38ns ; so the timing is met. Having a more complex design "removes" logic space and Lattice doesn't seem to be able to do large physical path delays any more.
