Here what I got calling the fft_biplex_real_2x from the command window:
>> fft_biplex_real_2x_init(gcb,...
'FFTSize', 5, ...
'input_bit_width', 18, ...
'coeff_bit_width', 18, ...
'quantization', 'Truncate', ...
'overflow', 'Wrap', ...
'add_latency', 1, ...
'mult_latency', 2, ...
'bram_latency', 2, ...
'arch', 'Virtex5', ...
'opt_target', 'Multipliers', ...
'coeffs_bit_limit', 7, ...
'delays_bit_limit', 8, ...
'specify_mult', 0, ...
'mult_spec', 0)
??? Error using ==> reuse_block at 42
biplex_core block (mask) does not have a parameter named 'conv_latency'.
Error in ==> fft_biplex_real_2x_init at 105
reuse_block(blk, 'biplex_core', 'casper_library/FFTs/biplex_core', ...
The 'biplex_core' block seems to have the same behaviour or, better,
fft_biplex_real_2x inherits troubles from it, but I don't know if it is
the root of the problem...
Cheers,
Andrea
