<ul>
	<li>Stephen has a new design that is trying something very odd

</li>
	<li>Difference between different grounding techniques</li>
	<li>8 layer monster board with multiple power supplies - low noise</li>
	<li>Parker likes to think of these problems as the extremes of certain examples as a way to think about what happens

<ul>
	<li>Take a "star" topography ground for instance

<ul>
	<li>Make the trace lengths that connect to the "star" really small</li>
	<li>Make the star point really "big"</li>
	<li>This is vias connections direct to a plain</li>
