Figure 8 shows the write timing for level-sensitive, sin-
gle-port RAM.
The relationships between CLB pins and RAM inputs and
outputs for single-port level-sensitive mode are shown in
Figure 9 and Figure 10 show block diagrams of a CLB con-
gured as 16x2 and 32x1 level-sensitive, single-port RAM.
Initializing RAM at Conguration
Both RAM and ROM implementations of the XC4000
Series devices are initialized during conguration. The ini-
tial contents are dened via an INIT attribute or property
attached to the RAM or ROM symbol, as described in the
schematic library guide. If not dened, all RAM contents
are initialized to all zeros, by default.
RAM initialization occurs only during conguration. The
RAM content is not affected by Global Set/Reset.
