CPU Debug Connector Pinout
Figure 2-10shows J12, the 16 pin header used to debug the operation of software in the CPU. This is done using debug tools such as Parallel Cable IV or third party tools. Refer to the PPC405 Processor Block Manual for more information on the JTAG debug-port signals.

CPU Debug Connection to XC2VP30
The connection between the CPU debug connector and the XC2VP30 are shown in Table 2-9. These are attached to the PowerPC™ 405 JTAG debug resources using normal FPGA routing resources. The JTAG debug resources are not hard-wired to particular pins, and are available for attachment in the FPGA fabric, making it possible to route these signals to whichever FPGA pins the user prefers.

PCI Bus
The ML310 board design provides the Xilinx Virtex-II Pro access to two 33MHz/32bit PCI buses, Primary 3.3V PCI Bus and a Secondary 5.0V PCI Bus. The FPGA is directly connected to the Primary 3.3V PCI bus while the 5.0V PCI Bus is connected to the Primary PCI Bus via a PCI-to-PCI Bridge. There are several PCI devices available on the PCI Buses as well as 4 PCI add-in card Slots. All PCI Bus signals driven by the XC2VP30 comply with the IO requirements specified in the PCI Local Bus Specification, Revision 2.2.
The majority of the ML310 features are accessed over the 33MHz/32 bit PCI Bus. The Virtex-II Pro Power PC405 Processors can gain access to the Primary PCI Bus through the EDK PCI Host Bridge IP. All PCI configuration and control can be performed via a PCI Host Bridge implemented in the FPAG fabric. The Primary PCI Bus is wired so that the FPGA fabric must used to provide PCI Bus arbitration logic. The EDK kit also provides PCI
