Worst case H.264 CABAC testing

Hi,
I want to test a H.264 CABAC decoding engine for the worst-case.
Is there any bitstream available that I can use for testing the worst
case scenerio? I know that it would be very difficult to get the worst
case bitstream, but still worth asking for. Also, is there any
bitstream which may not be for the worst case bitstream, but still
very computationally extensive to decode using CABAC?
Alternatively, is there any technqiue using which I can analyze if a
specific CABAC decoder can achieve required throughput in the worst
case.
I was thinking of using random totally bitstream to get maximum
uncorrelation, encode that bitstream, and try decoding it with CABAC
decoder. Any ideas if such scheme has already been employed and any
sound results for such schemes?
Any other tips related to CABAC testing, not necessarily related to
worst case testing, would be really helpful.
Thanks,
Sharjeel Saeed
