I'm a fairly experienced user of Quartus but I've never considered using "blocks" in block design files i.e. my design hierarchy consists of only symbols with a mixture of Verilog and graphic design modules "underneath" each symbol. I have never seen a need to use them.
My question is: does anyone routinely use blocks in their designs and what are the advantages/disadvantages of doing so?
It seems to me that they must be there for a good reason. I just can't see what that reason is and i think I may be missing out on something potentially useful.
When I say block I mean using the "block" tool not the "symbol" tool. Blocks are or can be connected together with "conduits" whereas I think symbols can only be connected with "bus" and "node" connections.
