a different assignment behavior in HDL is your assignment does not
take effect until a delta cycle of zero virtual time has passed. (did
you really looked at the previous postings? :)

x = 4 should be something like x <== 4 or x := 4 (the latter has been
taken by the assignment expressions though ...). Such that variable
initialization (=) and utilization (<==) can be differentiated.

Sad to see that's the case from you when it seems you barely even read
all of the postings in this thread.
