6.2.2 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.
