■ Write (MBps) and Read (MBps)—Show the number of bytes of data analyzed per
second.
Error Control
The Error control controls track transaction errors detected during analysis:
■ Detected errors —Displays the number of transaction 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 zeros.
Number of Addresses to Write and Read
The Number of addresses to write and read control determines the number of
addresses to use in each iteration of reads and writes. Valid values range from 2 to
524,288.
Data Type
The Data type control specifies the type of data contained in the transactions. The
following data types are available for analysis:
■ PRBS —Selects pseudo-random bit sequences.
■ Memory —Selects a generic data pattern stored in the on chip memory of the
Stratix IV GX device.
■ Math —Selects data generated from a simple math function within the FPGA
fabric.
The HSMC Tab
The HSMC tab allows you to perform loopback tests on the HSMC A and HSMC B
ports.
Figure 6–7 shows the HSMC tab.
