21.13.1.45 read_lsram

Description

This tcl command reads a specified block of large SRAM from the device.

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

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 for the user defined memory block.
port	string	Specifies the port for the memory block selected. Can be either Port A or Port B.
fileName	string	Optional; specifies the output file name for the data read from the device.
file	string	Optional; specifies the output file name for the data read from the device.


Return Type	Description
None	None

Error Codes


Error Code	Description
None	Parameter 'file' has illegal value.
None	Parameter 'fileName' has illegal value.
None	Port 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 LSRAM Block Fabric_Logic_0/U2/F_0_F0_U1/ramtmp_ramtmp_0_0/INST_RAM1K20_IP from the PolarFire device and writes it to the file output.txt.

read_lsram \
-name {Fabric_Logic_0/U2/F_0_F0_U1/ramtmp_ramtmp_0_0/INST_RAM1K20_IP} \
–fileName {output.txt}

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

read_lsram -logicalBlockName {Fabric_Logic_0/U2/F_0_F0_U1} -port {Port A}
