The SEM controller design can be challenging to implement, and the degree of difficulty is further influenced by:

  • Maximum system clock frequency
  • Targeted device architecture
  • Nature of your application
  • Level of device congestion

All SEM implementations need careful attention to system performance requirements. Hence, it is strongly recommended that the IP is integrated in the early stages of the design cycle. Pipelining, logic mapping, placement constraints, and logic duplication are all methods that help boost system performance.

Important: Do not add any pipeline registers between the SEM controller and ICAP and FRAME_ECC primitives as it alters and corrupts the behavior of the SEM controller.
