Control Description
Start Initiates DDR3 memory transaction performance analysis.
Stop Terminates transaction performance analysis.
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 of data analyzed per second.
  • Data bus: 72 bits (8 bits ECC) wide and the frequency is 1,066 MHz double data rate. 2,133 Megabits per second (Mbps) per pin. Equating to a theoretical maximum bandwidth of 136,512 Mbps or 17,064 MBps.
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—Inserts a one-word error into the transaction stream each time you click the button. Insert is only enabled during transaction performance analysis.
  • Clear—Resets the Detected Errors and Inserted Errors counters to zeroes.
Address Range (Bytes) Determines the number of addresses to use in each iteration of reads and writes.
