Chapter 3

Family Specific Considerations

This chapter provides important design information specific to the PCI interface targeting 
Virtex and Spartan devices. 

Design Support

Table 3-1

 provides a list of supported device and interface combinations. Each entry in the 

table consists of a device, a bus interface type, and two or three specific implementation 
files.
