9.3. Simulating the Ethernet to CPRI Dynamic Reconfiguration Altera FPGA IP Design Example Testbench

The Ethernet to CPRI dynamic reconfiguration block diagram for the example design simulation testbench is shown in the following figure:
Figure 26. PMA/FEC Direct PHY: Design Example Simulation Testbench

The testbench program monitors DR and protocol IP statuses and controls components via the Avalon® memory-mapped interface to access DR controller host-facing registers to initiate the DR process to the target profile.

The Protocol Driver block includes data packet generation/checker logic for Ethernet data packets, as well as PRBS generator and verifier for CPRI data.

The Ethernet to CPRI example design supports a one-channel interface with two data rate variants: 9.8G (Ethernet) and 4.9G (CPRI).
