What's wrong with an IDELAY element?

Sometimes just 30 degrees (10..40oC) is enough to bust overconfident engineers.

Absence of such thing in Lattice LCMXO2, which is currently a target FPGA.

Oh... Is it so that Lattice do not offer *any* kind of I/O delay management?
[edit] Seems like they do, (Technical Note TN1131, apr 2007) just LC series is not in the list of said tech note.

I have not looked in the details. 

Again, I know the answer "just use dedicated resources". There is no need to repeat it.

I was specifically looking for alternative solutions.
