        3D models help a lot, but it’s still a good idea to make a paper model of your PCB. You can find possible issues
        and fix them before your PCB goes into production. Have a look.

Checking your PCB from a Mechanical point of view

<div class="entry-content">
    <div class="blog-content">
        <b>Don’t do this with your boards – this is just a test.</b><br><br>
        
        Do you know all the tough rules from PCB design guides – length matching, impedance, etc.? What do you think, how far you can go and brake them?<br><br> 

        I was curious. We have not finished our baseboard yet and I really wanted to test our Ethernet PHY. So I had an opportunity to wire up a magnetics to the 1Gb Ethernet PHY on the module and test it. And I did. See this picture:
    </div>
    <div class="blog-content-img-wrapper">
        <img src="https://assets.fedevel.com/blog/2019/10/1450e-1gb-ethernet-phy-wired-up-to-magnetics.jpg" alt="OLYMPUS DIGITAL CAMERA" />
    </div>
    <div class="blog-content-text">
        Do you know what? It worked! The Ethernet is running at 1Gb speed (even I have not used an exact impedance nor did a precise length matching). I have not measured the real throughput, but it works.<br><br>

        <i>BTW: 10 years ago, I wired up DDR266 memories (swapped DQS & DQM signals between banks) and it worked too – at least on my table in the lab.</i><br><br>

        Please, this doesn’t mean, that you should not follow design guides. You definitely should. Why? It may look like everything is working ok, but that may not be true.<br>
        <b>Always try to design your board the best as you can.</b>
