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.
