21.15.4.6 Microchip Implementation Specifics

  • SDC accepts either –multiply_by or –divide_by option. In Microchip design implementation, both are accepted to accurately model the PLL behavior.
  • SDC accepts defining a generated clock on many sources using a single command. In Microchip design implementation, only one source is accepted.
  • The -duty_cycle , -edges and –edge_shift options in the SDC create_generated_clockcommand are not supported in Microchip design implementation.
