Product Specification
EARLY ACCESS
G50
Number of IDELAY
controllers instantiated.
Ignored it not Virtex-4
C_NUM_
IDELAYCTRL
2-6
(Virtex-4 only)
2 integer
G51
Includes IDELAY
primitive on GNT_N.
Set by tcl-scripts and
ignored if not Virtex-4.
C_INCLUDE_
GNT_DELAY
1=Include IDELAY
primitive
(Virtex-4 only)
0=No IDELAY primitive
0 integer
G52
Provides a means for
BSB to pass LOC
coordinates for
IDELAYCTRLs for a
given board to
EDK and is optional for
user to set LOC
constraints. This
parameter has no
impact on bridge
functionality.
