11.In Qsys, click Tools > System Console.

12.Before you execute scripts in System Console, navigate to the directory for the Tcl scripts, and then in

Qsys System Console window, click File > Execute Script.

13.To start the memory tests, run the run_sweep.tcl file from the tt_qsys_design\quartus_ii_projects_for_

boards\<development_board> \system_console directory.

When you run the run_sweep.tcl script, the System Console displays the progress of the tests in the

Messages tab. The tests perform test sweeps on the SDRAM by varying the memory block size and

memory block trail distance. When the tests finish successfully, Qsys generates a message that reports

successful completion.

Simulating Custom Components

You can simulate a custom component with Qsys and the Avalon Verification IP Suite. You use Qsys to

generate a testbench system for the design under test, and then perform a functional simulation with the

ModelSim-Altera simulator. The Qsys-generated testbench uses the Avalon Verification IP Suite

components.

Generate a Testbench System in Qsys

The custom pattern generator generates high-speed streaming data for testing memory devices. The soft-

programmable custom pattern generator can generate multiple test patterns, and is programmed with the

pattern data and pattern length. When the end of the pattern is reached, the custom pattern generator

cycles back to the first element of the pattern.
