Control
Description
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 1066 MHz
double data rate. 2133 Megabits per second (Mbps) per pin.
Equating to a theoretical maximum bandwidth of 136512 Mbps or
17064 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 Error—Inserts a one-word error into the transaction stream
each time you click the button. Insert Error is only enabled during
transaction performance analysis.
• Clear—Resets the Detected errors and Inserted errors counters to
zeroes.
Number of Addresses to Write
and Read
Determines the number of addresses to use in each iteration of reads
and writes.
