PLB PCI Full Bridge (v1.00a)

Port and Parameter Dependencies

The dependencies between the IPI v3.0 Bridge design port (i.e., I/O signals) and parameters are shown in Table 1.

Table 3: PLB PCI Bridge Parameters-Port Dependencies

	Bridge Features Parameter Group
				The set of PLB/IPIF BAR-parameters of
				N = 0 to C_IPIFBAR_NUM-1 are
				meaningful. When C IPIFBAR NUM <
				6, the parameters of N =
G1	C_IPIFBAR_NUM	G5-G25		C IPIFBAR NUM up to and including 5
				have no effect. If C IPIFBAR NUM = 6,
				the set of PLB/IPIF BAR-parameters of N
				= 0 to 5 are all meaningful (i.e., G2-G25
				are meaningful).
