Hi Dave, Thanks for the reply! Tut3 is now working so now to try the other design. The update_casper_blocks is a much better solution than it used to be last I used the toolflow. Also nice FFT test. The commit hash for the mlib_devel I was using was the casper-astro #4c7ba5efb421fda1cec0640cf0e3

Hi all, I've recently (after a long CASPER hiatus) tried to recompile a design from 2012 using the latest mlib_devel (from casper-astro git repo), Xilinx 14.7 and Matlab 2012b. I find I get very strange results from the PFB/ wideband real FFT. I would describe this vaguely as a lot of zeros, wit
