TMS320F28069M: EVM Board Layout Design verification

Part Number: TMS320F28069M

Hi,

We are doing the design for TMS320F28069U-PZPA with reference to Texas instruments F2806x ISO ControlCard design Documents.

We have one doubts on the Gerber data. PFA the image from Gerber Data and also Gerber files, In the Gerber data, Layer 2 and Layer3 are only Wider Tracks not the complete copper Plane right?

FAB_{TEX116}F2806xISOcontrolCARDr0.4.zip

Can we do dedicated complete copper plane for Layer2(Ground) and Layer3(Power)? 

Thanks and regards,

Naveen K

    I believe the Gerber files are showing you a "negative" view where the black indicates copper and the color (purple or green) is the absence of copper. It looks like layer 2 has two separate ground regions. And layer 3 is a combination of GND and PWR planes.

    You can do that, although typically you'd want to have a GND beneath signal routes. Of course, there are some tradeoffs with a 4-layer board where having a GND beneath the route may not be possible.
