Im using Cyclone III EP3C120F780I7.

under what circumstances the code will be hard to synthesize? will that lead to failure in routing the signals?

Hi,

Long elaboration and synthesis runs could have a lot of reasons. Failure in routing could be caused by different reasons. Which design language are you using ? I would try to

setup test projects for each main block of your toplevel, in order to find out which block

causes the long runs.

Kind regards
