To support a new package type one would typically start with designing the socket
card. The pinout between the socket card and routing card is not defined and left to
the designer. An example is given in figure 6-1
Next is the design of the routing card (figure 6-3). The routing cards role is to connect
each pin from the socket card to the corresponding pin on STK600. In addition to
decoupling etc, the routing card should also fan-out the correct signals to
programming headers.
Each card in the stack has its own board_id pins, the routing card is responsible for
passing on the signal to the socket card.
Route BOARD_ID0 to BOARD_ID6 and VCC to BOARD_ID7
Route BOARD_ID0 to both BOARD_ID2 and BOARD_ID3.
