4.2.6.1. The DDR5 COMP Tab

Figure 19. The DDR5 COMP Tab

The following sections describe controls on this tab.

Start

Initiates DDR5 memory transaction test.

Stop

Terminates transaction test.

Test times

Number of times that write and read DDR once.

Test Control

  • Test Size: You can choose the size of the memory to test. The available options are 64 KB, 256 KB, 1 MB, 4 MB, 16 MB, 64 MB, 256 MB, 1 GB, and 4 GB (default).
  • Offset (Hex): You can define the memory start address to test.
  • Test Mode: Infinite Read and Write (default), Single Read and Write.
  • Test Pattern: PRBS (default), User Defined Constant, Walking '0', Walking '1'.

Error Control

This control displays data errors detected during analysis and allows you to insert errors:

  • Detected Errors: Displays the number of data errors detected in the hardware.
  • Inserted Errors: Displays the number of errors inserted into the transaction stream.
  • Insert: Insert a one-word error into the transaction stream each time you click the button. The Insert error is only enabled during transaction performance analysis.
  • Clear: Resets the Detected Errors counter and Inserted Errors counter to zeros.

Performance Indicators

These controls display current transaction performance analysis information collected since you last clicked Start:
  • Write, Read, and Total performance bars: Show the percentage (%) of maximum theoretical data rate that the requested transactions are able to achieve.
  • Write (MBps), Read (MBps), and Total (MBps): Show the number of bytes analyzed per second.
