21.13.1.8 debug_iod

Description

This Tcl command gets the training data from the CORERXIODBITALIGN IP and displays Eye Width and Sampling Edge.

debug_iod [-deviceName "device name"] \
          -iod_type {RX_DDRX_B_G_DYN/RX_DDRX_B_R_DYN/RX_DDRX_B_G_FDYN} \
          -inst_path {PF_IOD_GENERIC_RX instance path from Top}

Important: CORERXIODBITALIGN IP must have the output debug pins either connected or promoted to the top for SmartDebug to detect and identify the debug signals. The following pins must be configured for CORERXIODBITALIGN for IOD training to succeed and to be able to perform tasks such as reading delay taps, left taps, right taps, and bit align errors:

RX_BIT_ALIGN_LEFT_WIN
RX_BIT_ALIGN_RGHT_WIN
BIT_ALGN_ERR
DEM_BIT_ALGN_TAPDLY
BIT_ALGN_DONE
BIT_ALGN_START

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.
iod_type	string	Specifie iod type. Valid types are: RX_DDRX_B_G_DYN, RX_DDRX_B_R_DYN and RX_DDRX_B_G_FDYN.
inst_path	string	PF_IOD_GENERIC_RX instance path from Top.


Return Type	Description
None	None
