CLD exam- Wire bends/overlaps

[Melchizedek24]

Hi everyone , i m preparing for my CLD exams. When i went through exam instructions, it is mentioned as no wire bending/ wire overlapping in programs. I tried to avoid wire bending in my practice programs but not able to do a program without bending wires or running overlapping wires in program(especially for shift registers). What i really want to know is any program can be done without wire bends or overlaps?Even for Bundle cluster , we need to bend wires since i/p and o/p locations are different. So kindly clarify my doubt since this wire bending is making me worried a bit for my exam preparation..

We all know wires have to bend sometimes.  But, unnecessary wire bends and unnecessary wire crossings show a lack of style and make your code look anywhere between sloppy and unreadable. Any prospective CLD should code cleanly and know how to leave space for function / vi inputs and outputs and choose a good layout naturally.

So just do your best to avoid them.  I would think of it as "unnecessary" bends and crossings.  I think if you go in with that mindset, you'll be okay.

I'd avoid nodes overlapping wires though. At least in the CLD.

I gave up on routing my wires around structures, although I do have strict rules when wiring behind a structure (e.g. the wire should be straight).

Again: no nodes\structures overlapping wires (or nodes\structures) for the CLD.

I agree the 3rd one is the best. As to the others, the 1st is prettiest, but i loathe the hidden wire. The 2nd is clear, but not beautiful.

It gets worse if there are more shift registers. 1 gets uglier, 3 impossible (for instance if more than 1 wires are used n the structure.

I've been told JeffK uses a stacked sequence structure:

This might be the purest solution. To me it doesn't really add enough to do the extra work.

EDIT: I won't be surprised if you loose CLD points for using a SSS, even though it's usage here is appropriate.

Sometimes i wire through a case even if nothing happens just to keep the wires straight. ^^

If not used at all I'd wire behind it.

But if a property is read in the structure (from a class wire) I do often wire it through even though the output didn't change...

In the above mentioned example, innstead of 3 shift registers, can we club them into a songle cluster and pass down as a single line? would it look good if it is used as a cluster?

Thanks for the tip.
