Hi - that's annoying - sorry! No, you can't easily feed a FEAT4 design.mat
into FEAT5 without fiddling around with the TCL. I suggest that you send
me (email me directly) the design.fsf file and all associated custom
timing files so that we can debug at this end. (You should be able to save
the design.fsf file hopefully even though feat_model crashes).
Thanks, Steve.
