Synthesis

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

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

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