[casper] FFT drawing issues (wideband real)

[Suraj Gowda]

Hi casperites,

When trying to draw a 16-input real FFT, I get the following error  
message in 10.1 about 109830498 times:

Warning: In instantiating linked block
'spec_256ch_250MHz_clk/fft_wideband_real/fft_direct/butterfly1_5/ 
twiddle/convert_of2/never' : Xilinx Constant Block Block block
(mask) does not have a parameter named 'SID'.

I do not get the same error message on a different 10.1 machine using  
a (much) older library version or in 11.x.

Any suggestions appreciated!

Thanks,
