7. Prototyping Area

The prototyping area accommodates 0.10-inch spaced ICs. The kit contains headers that can be soldered to the breakout area, if desired. Power and ground buses are located at the top and bottom edges, respectively, of the prototyping area.

8. VCCO-Enable Supply Jumpers

Virtex-4 series devices have 9 to 17 SelectIO banks, labeled 0 through 16, each with a VCCO-enable supply jumper. The VCCO-enable supply jumpers can connect each bank to one of the two onboard supplies, VCCINT or the VCCO supply. These jumpers must be installed for the Virtex-4 device to function normally.

9. VBATT

An onboard battery holder is connected to the VBATT pin of the DUT. If an external power supply is used, the associated jumper must be removed and instead use a 12 mm lithium coin battery (3V).
