A question on chip's parts sequesnce (RAM8)

[coykto]

Hi, i've found this course few days ago and i really love it, thanks to everyone involved in it's creation. Ok, so i just finished RAM8 chip, parts look something like this:

DMux8Way() // Selecting address to write to

Register() // Writing to appropriate address
Register()
...
Register()

Mux8Way16() // Reading some address

So i just wanted to check other people's implementations to see if it can be done more efficient, or easy and i found this code:

Register() // Writing to appropriate address
Register()
...
Register()

DMux8Way() // Selecting address to write to
Mux8Way16() // Reading some address


Almost the same, as you can see, but DMux8Way goes after writing register, so it seems like we would always write registers with load=0, since it's value not set in the first place. But i've tried that code and it worked just as my version.
I'm probably missing something, but i can't see what. Is order of parts is not important? I can post the full code if needed, i just didn't want to create spoilers.

A great question! Remember, HDL is really a representation of real hardware - not software code. While many programming languages are indeed procedural, where order matters, HDL is not procedural. It is declarative.

Imagine you are sitting at a workbench wiring all this stuff together. The order in which you wire it all up doesn't quite matter. As long as all the parts are connected, you're good.

Oh right, that makes sense. Thank you!
