can i use halui.mode.is-manual more then once.

Not by name, but you can re-use the signal name.

So, if you have somewhere

net sig1 halui.mode.is-manual and2.0.in0

Then somewhere else you could use

net sig1 and2.1.in0

because the "value" of sig1 is always the same as halui.mode.is-manual.

What I would normally do, though is

net mode-check halui.mode.is-manual => and2.0.in0 and2.1.in0 and2.2.in0

The order you place the pins has no meaning at all. The arrow is ignored by the processor and has no meaning at all.

net must be first.
signal-name must be next

So:

net my-signal-name and2.2.in1 <= halui.mode.is-manual
net my-signal-name and2.2.in1 => halui.mode.is-manual
net my-signal-name halui.mode.is-manual <= and2.2.in1
net my-signal-name halui.mode.is-manual => and2.2.in1

are all the same.

second & third position = in or out
depending on the position of the sig and pin.

No, absolutely not.

The position has no control over whether something is an input or an output.

A pin is either an input or an output. This is fixed and immutable, nothing that you can do can change the direction of a pin.
The position in the line is irrelevant.
The position in the line does not matter.
It is completely unimportant where in the sequence you put the pins. They are an input or an output dependent only on their hard-coded definition.
Some pins are inputs, some pins are outputs.

You can have one or fewer output pins on any "net" line
You can have zero or more input pins on any "net" line.
You must have a signal name after the "net command"
You can arrange the order of the input and output pins on the line in any way that suits you.
You will quite often see lines like this:

net example input-pin-1 <= shared-output-pin => input-pin-2

You keep making this statement, and we keep correcting you.

thanks BigJohnT and andypugh

i'll keep at it. i just can't get my head around what does what.
the position of the pin and sig mean nothing.and this <== and ==> mean nothing(<==> i got awhile back i shouldn't have
used em here because it just confuses me

The signal name MUST be next after the word net. You can not put it anywhere else on the line.

that being said,i'm trying to figure out what "happens" when switching sig and pin position.
i need to see(in my head) "what" is happening. ya'll can wire this from scratch. ya'll can "see"
the "wiring", where it goes,what it does.

What happens when you switch the signal name with a pin is EMC crashes and won't run.

i hope i'm making this clearer, as i think it is "me" not explaining myself in "yall" terms.
took me awhile to figure out what i pin and what is sig. i Do really understand that part.
but i'm not explaining this correctly and it gets me deeper into trouble
i really do appreciate all ya'll time and a lot of patience:)
Thanks !

I know your having a hard time getting a grasp of this... but you are making progress.
