The twiddle block does show up in the Casper library. I'm not entirely sure how
to correctly run the mask script from the MATLAB command line, but I tried the
following (my model is called 'sysgen_scratch').
----
>> fft_init(sysgen_scratch/fft)
??? Error due to multiple causes.
Caused by:
The LinkStatus can be set only for a linked block.
Error in
'sysgen_scratch/fft/fft_biplex0/biplex_core/fft_stage_3/butterfly_direct/twiddle':
Initialization commands cannot be evaluated.

I suspect this isn't what you meant.
