21.13.1.46 read_usram

Description

This tcl command reads a uSRAM block from the device.

read_usram [-deviceName "device name"] \
           [-name "USRAM block name"] \
           [-logicalBlockName "USRAM user defined block name"] \
           [-port "USRAM port name"] \
           [-file "Data file name"] \
           [-fileName "Data file name"]

Phisical block
read_usram -name {RAMS_LSRAM_URAM_0/PF_DPSRAM_C0_0/PF_DPSRAM_C0_0/PF_DPSRAM_C0_PF_DPSRAM_C0_0_PF_DPSRAM_R0C0/INST_RAM1K20_IP}

Arguments


Parameter	Type	Description
deviceName	string	Optional user-defined device name. The device name is not required if there is only one device in the current configuration, or a device has already been selected using the set_debug_device command.
name	string	Specifies the name for the target block.
logicalBlockName	string	Specifies the name of the user defined memory block.
port	string	Specifies the port of the memory block selected. Can be either Port A or Port B.
file	string	This parametr is ptional. Specifies the output file name for the data read from the device.
fileName	string	This parametr is ptional. Specifies the output file name for the data read from the device.


Return Type	Description
None	None

Error Codes


Error Code	Description
None	Missing argument. Must specify '-name' or '-logicalBlockName'.
None	Error: Parameter 'param_name' is not defined. Valid command formatting is'read_usram [-deviceName "device name"] [-name "USRAM block name"] [-logicalBlockName "USRAM user defined block name"] [-port "USRAM port name"] [-file "Data file name"] [-fileName "Data file name"]'.
None	Parameter 'name' has illegal value.
None	Error reading USRAM block value from the device: Target block not found in debug file.
None	Parameter 'file' has illegal value.
None	Port_name is an invalid Port name.
None	Parameter 'port' has illegal value.
None	RAM port name must be specified.
None	LSRAM block cannot be read. Use phyical block option to read.

Example

Reads the uSRAM Block Fabric_Logic_0/U3/F_0_F0_U1/ramtmp_ramtmp_0_0/INST_RAM64x12_IP from the PolarFire device and writes it to the file sram_block_output.txt.

read_usram \
-name {Fabric_Logic_0/U3/F_0_F0_U1/ramtmp_ramtmp_0_0/INST_RAM64x12_IP} \
–fileName {output.txt}

This example reads the uSRAM logical Block {Fabric_Logic_0/U3/F_0_F0_U1} from {Port A}.

read_usram -logicalBlockName {Fabric_Logic_0/U3/F_0_F0_U1} -port {Port A}
