1.4. Creating Qsys Systems

The data pattern generator and data pattern checker are design blocks for the memory tester system. In this tutorial, you learn to instantiate, parameterize, and connect components by creating the data pattern generator and data pattern checker Qsys systems.
  • Data pattern generator—The data pattern generator generates high-speed streaming data, which performs either as a PRBS, or as a soft programmable sequence, for example, “walking ones.” The design sends the data with an Avalon-Streaming (Avalon-ST) connection to the pattern writer of the memory master and control logic. The data pattern generator writes the data to memory based on commands issued by the controller logic. When the design writes the data to memory, the pattern reader logic reads the contents back and sends it to the data pattern verification logic.
  • Data pattern checker—The data pattern checker accepts the data read back by the pattern reader from an Avalon-ST connection. The design verifies the data pattern to ensure that the pattern it writes to memory is identical to the data that it reads back.
