Table 1: PLBV46 PCI Bridge Interface Design Parameters (Cont’d)
Generic Feature / Description Parameter Name
Allowable Values
G48 PCI initiated prefetch
C_PCI_DISCARD 10 or 15
Discard Timer value (power _TIMER
of 2 in PCI clocks)
G49 PLB initiated prefetch
C_PLB_DISCARD 10 or 15
Discard Timer value (power _TIMER
of 2 in SPLB clocks)
G50 Number of IDELAY
C_NUM_
controllers instantiated.
IDELAYCTRL
Ignored if not Virtex-4 or
Virtex-5 FPGAs
2-6
(Virtex-4 or Virtex-5 FPGAs
only)
G51 Includes IDELAY primitive C_INCLUDE_
on GNT_N. Set by
GNT_DELAY
TCL-scripts and ignored if
not Virtex-4 or Virtex-5
FPGAs.
1=Include IDELAY primitive
(Virtex-4 or Virtex-5 FPGAs
only)
0=No IDELAY primitive
G52 Provides a means for BSB C_IDELAY
to pass LOC coordinates for CTRL_LOC
IDELAYCTRLs for a given
board to
EDK and is optional for user
to set LOC constraints. This
parameter has no impact on
bridge functionality.
