DSP builder blocks for simulink models

That's a pretty vague question. I would take a look at http://www.altera.com/literature/ug/ug_dsp_builder.pdf . The 2nd chapter talks about creating a simple design including Input and Output blocks.

DSP Builder input/output blocks are needed to transform Simulink datatype (type double, single, ... etc.) into DSPB Datatype. Therefore, you would need input/output blocks at the boundaries of your hardware (built by DSPB blocks)...

wronghorizon, Thanks for this post. I looked everywhere to find this info, and after reading this above, I was able to get DSP Builder to work with SImulink. Thanks!
