Hi,

Sorry for the delay. For your information, as per my discussion with Factory, currently they are having bandwidth limitation to perform further investigation into this legacy IP. Sorry for the inconvenience.

As a workround, I have tested running the IP generated in Quartus Standard Edition and observe that the simulation seems to be working. However, in the Standard Edition, there is no 802.11n standard.

The following are some workarounds which might need your help to explore:

1. Just wonder if the other modes available in Quartus Standard Edition ie DOCSIS 3.1, NASA GSFC-STD-9100 or WiMedia 1.5 would work for you?

2. Instead of testing on simulation, can you try to run on hardware to see if your 802.11n mode work on hardware just in case it is IP simulation bug only.

Sorry for the inconvenience.
