Two FFT blocks of different sizes exhibit problem

Design has FFT blocks of different sizes sizes. Finding incorrect results unless the sizes are the same. I am using version 13 DSP Builder, and have not synthesized the design, but have simulated t...

Model Referencing isn't supporting in DSP Builder (Standard or Advanced). Best solution to achieving a similar result is to create library blocks to use, and to make use of subsystems. For FFTs, there should be a large number of FFT examples available to start from, and these are generally open to inspection by looking under the masks.
