During configuration global configuration control signals hold the core fabric in a frozen state to prevent electrical contention.
The LSMs work in parallel to asynchronously unfreeze the sectors. Within a sector the LSM unfreezes LAB rows and registers
in the LABs sequentially. The LSMs work to unfreeze the fabric in parallel across all sectors without synchronization.
Consequently, logic in different sectors or in the same sector but in different rows could begin to operate while other logic is
still frozen. The
INIT_DONE
signal asserts when all the LSMs have entered user mode.

The following topics provide more detail about device configuration and initialization, and possible consequences if you do not
use the Reset Release IP to hold the Intel Agilex device in reset until entire fabric enters user mode.
