Hi Andreas,

thanks! Not disappointing at all - I understand the compromises required and it's nice to know
there's a plan that might work around the limit.

Cheers,
Si

Hi,
Sorry for the slow response - I have been travelling for work.
OK, Still same comment re: Figure 5: PEC Placement - diagram gives X spacings, but still needs Y spacings.
These are needed to lay out mating boards.
cheers,
Beau

Sylvain,
Do you prefer the 1.0V copper landing pad on the top or the bottom of the board?

Hi Tim,

Thanks for the suggestion. There are a couple of reasons we kept the 1P0V and VDD_DSP supplies separate.

1.) This allows us to potentially tune the Epiphany voltage at run time to optimized energy usage in idle and during operation.
2.) The Epiphany chip can draw over 1A during peak operation, so it really needs it's own separate rail. (since we picked a PMIC with a 1.5A peak)

(btw it' not possible to short the regulator outputs together)
