2. Apply the Connect-5 algorithm to generate a preliminary pin-
assignment result. For example, to generate a pin-assignment result
to the multiwell chip in Figure 6.1, a preliminary result is first
derived, as shown in Figure 6.4a. Note that since the pin assignment
can be carried out by copying and shifting of the bagua repetition, it
takes O(
N
2
) time for an
N
×
N
array.
3. Next, consider the electrodes that will make up the segregation
regions and wells in the multiwell design. Disconnect these elec-
trodes from their control pins
(see Figure 6.4b)
.
This step also takes
O(
N
2
) time for an
N
×
N
array.
Finally, we group the electrodes occupied by each well and connect each group
to a single control pin. For independent control of each well, the group control
pins must be different not only from each other but also from the pins assigned
to the electrodes on the transportation pathway. The modified pin-assignment
