data are displayed. Note that the timestamp is updated to reflect the time between displayed cycles.

6.2 Viewing Raw DDR3 Data using B_DDR3D_XX Supports

In order to make the display of DDR3 data more user-friendly the raw data from the Address, all Data and other groups is suppressed in the B_DDR3D_2D Listing display. Instead the postprocessing display software formats and reorders the data to tag and display valid DDR3 Address, Commands and Data. In the case of the B_DDR3D_2D supports, which stores two Read and two Write data cycles in each TLA Sample location, the data is reordered chronologically in the display with the oldest data being shown on the line above the newer data.

To see the raw data using the Interposer support package perform a right mouse click in the Listing window, select Add Column… then click on the group to be added. Refer to the TLA User’s Manual or online help for further information on added or deleting data groups.
