2024.1 English


AMD FPGAs are configured by loading design-specific configuration data, in the form of a bitstream file, into the internal memory of the hw_device. The hw_cfgmem defines a flash memory device used for configuring and booting the AMD FPGA in the Hardware Manager feature of the Vivado Design Suite.

The hw_cfgmem object is created using the create_hw_cfgmem command. Once the hw_cfgmem object is created, and associated with the hw_device, the configuration memory can be programmed with the bitstream and other data using the program_hw_cfgmem command.

The hw_cfgmem object is associated with the specified hw_device object through the PROGRAM.HW_CFGMEM property on the device object. To work with the hw_cfgmem object, use the get_property command to obtain the object from a hw_device:

get_property PROGRAM.HW_CFGMEM [current_hw_device]


You can use the report_property command to report the properties assigned to a hw_cfgmem object. Refer to the Vivado Design Suite Tcl Command Reference Guide (UG835) for more information. The properties on the hw_cfgmem object include the following, with example values:

Property	Type	Read-only	Visible	Value
CFGMEM_NAME	string	true	true	28f00ap30t-bpi-x16_0
CFGMEM_PART	cfgmem_part	false	true	28f00ap30t-bpi-x16
CLASS	string	true	true	hw_cfgmem
NAME	string	false	true	28f00ap30t-bpi-x16_0
PROGRAM.ADDRESS_RANGE	string	false	true	use_file
PROGRAM.BIN_OFFSET	int	false	true	0
PROGRAM.BLANK_CHECK	bool	false	true	0
PROGRAM.BPI_RS_PINS	string	false	true	NONE
PROGRAM.CFG_PROGRAM	bool	false	true	0
PROGRAM.ERASE	bool	false	true	1
PROGRAM.FILE	string	false	true	
PROGRAM.FILE_1	string	false	true C:/Data/Vivado_Debug/kc705_8led.mcs
PROGRAM.FILE_2	string	false	true	
PROGRAM.VERIFY	bool	false	true	0
PROGRAM.ZYNQ_FSBL	string	false	true	

To report the properties for a hw_cfgmem object, you can copy and paste the following command into the Vivado Design Suite Tcl shell or Tcl Console when the Hardware Manager feature is open:

report_property -all [get_property PROGRAM.HW_CFGMEM [current_hw_device] ]
