Hi Chao, This is actually indeed behaviour. In the library, the fft blocks are empty shells. When you configure them in a design (setting input bitwidth, binary point, npoints, etc) they should redraw themselves with ports. Note that for a big fft this can take a few minutes.
Let me know if this isn't what happens for you Cheers Jack On Wed, 26 Jun 2019, 2:56 pm Chao Liu, <[email protected]> wrote: > Hi all, > > > I was trying to setup casper and matlab 2016b on the ubuntu 16.04 running > on Virtual box. > > > I followed the steps at https://casper-toolflow.readthedocs.io/en/latest/ > . > > > After matlab opened, I found that the FFT blocks in CASPER library do not > have any ports shown.
