Control Pins and Attributes
Virtex-II SelectRAM memory has two independent ports
with the control signals described in
inputs including the clock have an optional inversion.
Table 21: Control Functions
Initial memory content is determined by the INIT_xx
attributes. Separate attributes determine the output register
value after device configuration (INIT) and SSR is asserted
(SRVAL). Both attributes (INIT_B and SRVAL) are available
for each port when a block SelectRAM resource is configured
as dual-port RAM.
Locations
Virtex-II SelectRAM memory blocks are located in either
four or six columns. The number of blocks per column
depends of the device array size and is equivalent to the
