Description
Set or return the current hardware cfgmem object.
The process whereby the design specific data is loaded or programmed into the AMD FPGA is called configuration. The create_hw_cfgmem command defines a flash memory device used for configuring and booting the FPGA device.
When a new hw_cfgmem object is created, it becomes the current hw_cfgmem object. You can use the current_hw_cfgmem to return the current hw_cfgmem object, or you can specify a hw_cfgmem object, as returned by get_hw_cfgmems, to change the current object.
After the hw_cfgmem object is created, and associated with the hw_device, the configuration memory can be programmed with the bitstream and other data from a memory configuration file created with the write_cfgmem command.
The hw_cfgmem object is programmed using the program_hw_cfgmem command.
This command returns the current hardware cfgmem as an object, or returns an error if it fails.
Arguments
-hw_device <arg> - (Required) Specify the hw_device object to set the current_hw_cfgmem on. The hw_device must be specified as an object as returned by the current_hw_device or get_hw_devices commands.
-quiet - (Optional) Execute the command quietly, returning no messages from the command. The command also returns TCL_OK regardless of any errors encountered during execution.
-verbose - (Optional) Temporarily override any message limits and return all messages from this command.
set_msg_config command.<hw_cfgmem> - (Optional) Specify the hw_cfgmem object to use as the current configuration memory for programming and debug. The hw_cfgmem must be specified as an object as returned by the get_hw_cfgmems command.
Example
The following example returns the current hardware cfgmem object:
current_hw_cfgmem
