AGND AND DGND
BOTH ARE FULL PLANES TAKING UP THE ENTIRE SPACE OF THE BOARD
COLORED OUTLINES ARE JUST WHERE COMPONENTS WILL CONNECT TO THEIR RESPECTIVE GND'S
TOP LEFT WHITE ARROW IS POINTING TO NET TIE'S CONNECTING ANALOG AND DIGITAL GROUND ONLY IN THAT AREA OF THE BOARD

GND and GND2 are 2 different ground planes with their own net. I have it like that on purpose to control return paths in different areas. I just want to connect them in this area but Kicad wont let me connect to planes with different via names. How am I supposed to do this?
Ads1299 on left.
MCU input pins on right.
SPI signals going between them on layer 1
Layer 2 is a ground plane
0.11mm dielectric between planes
Frequency of signals is around 60mhz. 8ns rise time.
DOUT is GREEN and returns to DGND pin on the ADS1299
DIN is BLUE and returns the the...
Does anyone have experience with faraday tape and is it good enough to block the signals in this video down to under 20uv, or .02mv if all exposed metal with signals running through it are covered?
