Description
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.
Related Objects
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]
Properties
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
C:/Data/Vivado_Debug/kc705_8led.mcs
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] ]
