custom streaming client interface) are identical, except for the bandwidth. The following sections first
describe the testbenches that include adapters and then describe the testbenches without adapters.
You can simulate the testbench that you generate with your IP core variation. The testbench illustrates
packet traffic, in addition to providing information regarding the transceiver PHY. The non-40AGBASE-
KR4 testbenches tie off the reconfiguration control interface for your IP core, and do not exercise
transceiver reconfiguration. However, the 40GBASE-KR4 testbench exercises auto-negotiation and link
training, in addition to generating and checking packet traffic.
