21.13.1.7 debug_ddr

Description

This Tcl command retrieves/gets the training data from the Training IP and displays the status of different stages of training along with the eye width chart.

debug_ddr [-ddr_type type_of_ddr] \
          [-data_width width] \
          [-slot memory_slot] \
          [-inst_path ddr_instance_path_from_top] \
          [-frequency frequency]

debug_ddr [-deviceName "device name"] \
          -ddr_type "DDR Type" \
          -data_width "integer value" \
          -slot "DDR Slot" -inst_path \
          "Instace Path from Top" \
          -frequency "decimal value"

Arguments


Parameter	Type	Description
ddr_type	string	Specifies DDR type. Supported DDR types are: DDR4/DDR3/LPDDR4.
data_width	integer	Specify data width. Supported data widths are 16, 32, and 64.
slot	string	Slot that is used for the memory (for example, NORTH_NE/NORTH_NW).
inst_path	string	The instance path is from top module.
frequency	double	Specifies frequency in MHz.


Return Type	Description
None	None

Error Codes


Error Code	Description
None	Required parameter 'ddr_type' is missing.
None	Required parameter 'data_width' is missing.
None	data_width: Invalid argument value: 'data' (expecting integer value).
None	frequency: Invalid argument value: expecting decimal value.
None	DDR Debug: Valid values for "-ddr_type" parameter are DDR3, DDR4, LPDDR3. Provided value is a Error: .
None	DDR Debug: Valid values for "-ddr_width" parameter for DDR3 are 16, 32 and 64.
None	Parameter 'param_name' is not defined. Valid command formatting is 'debug_ddr [-deviceName "device name"] -ddr_type "DDR Type" -data_width "integer value" -slot "DDR Slot" -inst_path "Instace Path from Top" -frequency "decimal value" '.

Example

This example gets the training data from the Training IP and displays the status of different stages of training along with the eye width chart:

debug_ddr -ddr_type {DDR4} -data_width 32 -slot {NORTH_NE} \
          -inst_path {PF_DDR4_C0_0} -frequency 800.00
