[US] Seeking participants with Eagle knowledge to participate in a user study

<< < (2/2)

A very cool idea. I could see this being functionally useful for people who do consulting and have a lot of relatively similar project types. Doing 500 projects all essentially different plays on the same theme great you can save time and simplify the process of schematic reuse.

This looks very similar in theme to Dip trace's hierarchical schematics which I've been making progressively more use of. At least that's what I'm most familiar with.

If it ended up integrated with that software I'd welcome it happily. Especially if it included some good version management. I'd love the ability to verify and track the usage of specific blocks so that I can integrate those sorts of designs more effectively. For instance with the power supply system in the example. It would be nice to have the ability to track and annotate different versions of the schematic such that I could say track if I've verified the schematic worked on a board. Sort by power output capabilities, BOM cost, with layout integration, layout area.

Again I can only see it being useful for people doing a lot of mostly the same designs, but that's not an insignificant number of people, otherwise things like favorite microcontrollers/ power regulators/ transistors wouldn't be a thing. While I can see where the pessimistic people are coming from, I think it's a great first step towards something incredibly useful. On my to learn list has been PCBHDL, I have a friend who as I see it needs ~500 different boards designed, but each one is really similar, but can't be made to be the same. Including integration to allow these blocks to be connected with something like a PCB HDL language could up its usefulness quite a bit to those people.

Wish I could participate in your study unfortunately it's been so long since I've used Eagle that I'd be pretty well useless.

I'll be more specific about what I dislike here:
Too much abstraction leads to a lack of understanding.  The lego brick approach is all very well, but is heavily reliant on your i/o description being accurate and able to account for interactions between blocks.  The horribly fragmented schematic that was generated in the video is another barrier to understanding,  tracing nets across schematic snippets makes both board layout and fault finding very difficult.  This is a pet peeve of mine - I see this all the time where ppl draw a bunch of opamps scattered across a page and link them with net labels. Its impossible to get a good sense of the circuit flow, which is critical to good board layout.

The example video was pretty simplistic - what do you do when your microcontroller needs 4 different power supplies? What happens if you put too many loads inside your regulator block? What happens if you put too many loads on your GPIO?

Eagle bites already, but this...  ;D
I admit I didn't have the patience to watch more than a few sec of the tutorial though. But I can't see the point? Haven't been able to even understand what it was supposed to bring? And there is no description on the web site itself either, which kinda looks like a playground.  :-//

@ jgarzagu , you need to start from improving the sound quality , it is Absolutely horrible ( with capital A), i could not watch 10 sec of the video.

Hello jgarzagu,

As someone who has been working with PCB design for many years and always working on similar designs I absolutely see the value in what you are doing. Not in the current form though, but a mature tool that allowed to do this would be highly valuable. If you want to capture the attention of seasoned designers you would need to impress them. To avoid relying only on subjective opinions (and to gain confidence in your approach) it may be a good idea to set up benchmarks, i.e how much time would it take an engineer to complete a professional design with your tool vs with an existing tool? If you can address this specific question for a family of designs (say battery powered IoT sensors) your case would look more solid.

All the best,
