6.4.1 Peripheral and Embedded Hard Blocks

Various features of the architecture are located within the periphery but are not available within the FPGA array. These features can be incorporated within a block design but must be carefully enclosed to all the feature's I/Os within the block. Following are the list of features for PolarFire design:

  • DRI
  • APBM
  • SCB
  • ENFORCE
  • DEBUG
  • TVS
  • OSC_RC200MHZ
  • PF_SPI
  • SC_STATUS
  • UJTAG_SEC
  • SYS_SERVICES
  • VOLTAGEDETECT
  • OSC_RC2MHZ
  • INIT
  • TAMPER
  • PCIE
  • XCVR_PIPE_AXI0
  • XCVR_PIPE_AXI1
Note: While checking these interfaces in Chip Planner, flyline connections could converge at a single co-ordination. A large bus structure spread across an area is seen in the Chip Planner when the actual routing is viewed. If any I/O has an external name, off the chip, then it must be the same port name as in the top-level of the design.
