Each port accesses the same set of 18,432 or 36,864 memory cells using an addressing
scheme dependent on whether it is a RAMB18 or RAMB36. The physical RAM locations
addressed for a particular width are determined using the following formula (of interest
only when the two ports use different aspect ratios):
Table 4-8
All attribute code examples are discussed in the
Verilog Code
Additional RAMB18 and RAMB36 Primitive Design Considerations
INIT_xx attributes define the initial memory contents. By default, block RAM memory is
initialized with all zeros during the device configuration sequence. The 64 initialization
attributes from INIT_00 through INIT_3F for the RAMB18, and the 128 initialization
attributes from INIT_00 through INIT_7F for the RAMB36 represent the regular memory
contents. Each INIT_xx is a 64-digit hex-encoded bit vector. The memory contents can be
partially initialized and are automatically completed with zeros.
The following formula is used for determining the bit positions for each INIT_xx attribute.
Given yy = conversion hex-encoded to decimal (xx), INIT_xx corresponds to the memory
cells as follows:
•
•
For example, for the attribute INIT_1F, the conversion is as follows:
•
