Generic Parameter Name
Description
Allowable Values
Default Value VHDL Type
Non-HDL Generics
G68
C_BOARD⁽⁶⁾
Automatically
ml505, ml507, none
none
N/A
generates core level
constraints for the
selected board type.
This does not set
the Pin LOC
constraints.
G69
C_DEVICE ⁽⁶⁾
Used by the tools N/A
only. No user input
required.
Set by Tools N/A
1. This is a 32-bit address.
2. The width of this should match the address size (C_IPIFBAR_AS) for this BAR.
3. The range specified must comprise a complete, contiguous power of two range, such that the range = 2ⁿ and the n least significant bits
of the Base Address are zero.
4. The difference between C_IPIFBAR_n and C_IPIFBAR_HIGHADDR_n must be less than or equal to 0X1FFF_FFFF.
5. The minimum value of C_IPIFBAR must be greater than or equal to 0x1FFF.
6. This a NON_HDL generic used by the plbv46_pcie_v2_1_0.tcl to generate pcie core level constraints
7. The difference between C_ECAM_BASEADDR and C_ECAM_HIGHADDR must be less than or equal to 0x0FFF_FFFF and greater
than or equal to 0x001F_FFFF.
