1.2.5.3. Test Pattern Generator

Note: This module is only available in the design example when the duplex or simplex TX data path option is selected.

The test pattern generator generates either a parallel PRBS, alternate checkerboard, or ramp wave, and sends it to the transport layer during test mode. The test pattern generator is implemented in the top level RTL file, not in the Platform Designer project.

You can modify the test pattern generator RTL match your specifications. Furthermore, for parameters like M, S, N, and test mode, the test pattern generator shares the CSR values with the JESD204B IP core. This means that any dynamic reconfiguration operation that affects those values for the JESD204B IP core, affects the test pattern generator in the same way. This includes the pattern type (PRBS, alternate checkerboard, ramp) which is controlled by the test mode CSR.
