A combinational circuit?
A simple combination circuit should be written using an ASSIGN statement. A complex circuit should be written using an ALWAYS construct. 5.5.5 – My design takes too long to synthesize. Try to use bottom up approach by synthesizing the lower modules first to make sure that they are synthesizable. The bottleneck may show up in some of the lower modules, Try to fix them one by one. Use the incremental synthesis approach in the tutorial.
