Downdraft design questions

What program do you use to do your schematic drawings?

DIYLC - Do It Yourself Layout Creator ... several people on a tube amp forum were using it and I find it pretty easy to work with for freeware.

Code:

net zone0 <= ddraft4x2.0.trigger-0 net zone0 => hm2_7i76e.0.7i76.0.0.output-00

Where does this code go? Also, are these two lines of code specific to one zone? ie: will I need eight sections like this, one for each zone?

I am sure this will make more sense the once I grasp the first part.

Yes, you need 8 pins like that using the pin names from the component, like I created. zone0,zone1, .... zone7



Some people will connect pins using one line but I always like to do it on two lines.
The first line creates a signal. Eg solders a wire to the downdraft output pin if it were hardware.
The second line connects the other end of the wire to something. In this case a 7i76e output pin.

You have to decide which hardware pins you are using.

In which file does that code reside?

I think you said you already have the downdraft component set up so kepe it in that file. Check how I did it in the Sim I shared earlier. You could put it in your main hal file. don't forget to loadrt and addf the component too.
