I see combinational processes as an advanced topic.
I am surprised. For me it is something very obvious, if I have some
input signals ans some output signals and no storage elements between them.
Since Gandalf is targeting an fpga rich in flops,
what is the advantage of purposely inferring latches?
I never recommended to use latches for that example. I just wanted to
make it clear, what it means to model hardware. And as this result I
wanted to point out, that there are only these 3 pieces of hardware
available.
Gandalf is modeling a controller, not gates and flops.
All that is needed is a clean logic description and simulation.
For me hardware modeling means _everytime_ modeling gates and flops. I
can do it at a very low level (down to making synthesis for my own, what
is obviously not a good design practice) and if I know what I am doing I
can do it at higher level of abstraction.
I always (try to) have in mind, what kind of hardware I model, if I code
something.
Especially beginners tend to write VHDL like writing software if they do
it at a very high level of abstraction. For the first steps I think it
is a good idea make simple constructs, that easily show, what hardware
will be the result.
And small ones too
Yes, you are right. ;-)
