Hi Wang It may be that the version of the toolflow used to create that model, is not the same as what is on your machine. You may want to drag a new block in from your library, and then set the parameters to the same as the block in the model. There is also a script that will update the blocks in your model automatically - update_casper_blocks.m (I think).
