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.

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.

Start

The Start control initiates HSMC transaction performance analysis.

Stop

The Stop control terminates transaction performance analysis.

Performance Indicators

These controls display current transaction performance analysis information collected

since you last clicked Start:

■ TX and RX performance bars—Show the percentage of maximum data rate that

the requested transactions are able to achieve.

■ Tx (MBps) and Rx (MBps)—Show the number of bytes of data analyzed per

second.
