3.3.1. Simulation Results for Basic Mode

The generated example testbench is dynamic and has the same configuration as the IP.

In basic or pure streaming mode, the traffic generator generates 10,000 words and transmits to the IP once the TX and RX links are established. The words are then looped back to the RX MAC. The RX MAC then sends the words to the traffic checker for data verification. In the simulation results, you can find the following information:
  • TX and RX link status
  • Configuration settings of the IP
  • Number of words transferred per burst
  • Test results with the total number of words transferred and link latency value

The following are samples of simulation results for each design example variant.
