The connections on a PCB should be identical to its corresponding circuit diagram, but while the circuit diagram is arranged to be readable, the PCB layout is arranged to be functional, so there is rarely any visible correlation.

Are there any issues with copying the eval board as closely as possible?

Eval designs are rarely copyable because your design will usually have many additional components that impose many more layout constraints than the eval board designer had to deal with.


There is a distinction between evaluation boards and reference designs. Manufacturers will provide Gerber files for the latter, so that they can be copied exactly.


You should definitely copy PCB manufacturer's eval boards as closely as possible. The manufacturers make eval boards so that you can use their chips; they're happy to have you follow their examples.
