2.11.1 Host/System Slot Configuration
When installed in the System slot, the board provides the PCI arbitration and distributes the
required PCI clocks to the backplane, and to the PCI interface in the FPGA.
Figure 2-12: Block diagram for PCI System Slot connections
This requires the jumpers to be installed as follows:
JP7
1-2 and 3-4
JP9
1-2 and 3-4
JP10
1-2 and 3-4
Additionally, the PCI specification requires that the following system signals are pulled-up by
the card operating in the system slot:
PCI_FRAMEN
PCI_IRDYN
PCI_TRDYN
PCI_DEVSELN
PCI_STOPN
PCI_PERRN
PCI_SERRN
PCI_LOCKN
This can be achieved by installing the JP8 jumpers 1-2, 3-4, 5-6, 7-8, 9-10, 11-12, 13-14, 15-
16, 17-18 and 19-20.
In order to ensure that the PCIRSTN pin on the back plane is not left floating, it is also
