Initializing RAM at Configuration
Both RAM and ROM implementations of the XC4000
Series devices are initialized during configuration. The ini-
tial contents are defined via an INIT attribute or property

schematic library guide. If not defined, all RAM contents
are initialized to all zeros, by default.
RAM initialization occurs only during configuration. The
RAM content is not affected by Global Set/Reset.
