Paul,
My understanding is that a generated item can be a list of
declarations, instantations, continous_assignments, processe's
and other generate based statements ( for, case, block or if).
I dont think there is any limit on the number of statements inside
a generate_item, nor would it be fair to impose a restriction like
that.
Thanks,
- Krishna.
