Formatting BIN Files for Delivery to Internal Configuration Ports - 2022.2 English

Partial bit files have the same basic format as full bit files, but they are reduced to the set of configuration frames for the target region and restricted to the set of events that make sense for active devices. Partial bit files can be:

• Delivered to external interfaces, such as JTAG or slave configuration ports.
• Reformatted as BIN files to be delivered to the internal configuration ports: ICAP (7 series or UltraScale devices), PCAP (Zynq devices only) or MCAP (UltraScale devices only).

Generate BIN files using the write_cfgmem utility. Three options are critical:

• Set -format as BIN to generate that file type.
• Use -interface to select the SelectMap width, and use SMAPx32 for PCAP or MCAP for UltraScale ICAP.
  • SMAPx16 and SMAPx8 (default) can also be used for the 7 series ICAP.
  • SMAPx8 is required for 7 series encrypted partial bitstreams.
• You must use -disablebitswap to target the PCAP or MCAP.

write_cfgmem -format BIN -interface SMAPx8 -loadbit "up 0x0 <partial_bitfile>"

write_cfgmem -format BIN -interface SMAPx32 -loadbit "up 0x0 <partial_bitfile>"

write_cfgmem -format BIN -interface SMAPx32 -disablebitswap -loadbit "up 0x0 
<partial_bitfile>"
