1.2 Synthesis

During synthesis, Libero SoC software adds BLOCK_INTERFACE_I* instances to the block. These instances are virtual buffers added to:

Improve timing values for the block
Provide a clear interface to floorplan
Help with clustering constraints

Important: The BLOCK_INTERFACE_I* instances are removed when the block is published.
