4.5. Detailed Description of Device Configuration

Each Local Sector Manager (LSM) configures its own sector. A sector comprises multiple logic array block (LAB) rows. A logical function can span multiple rows and multiple sectors.

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.
