Problem with HIL, DSP_Builder and Stratix IV GX

Hi, I use Quartus II 10.1 SP1, DSP_Builder 10.1 SP1, Matlab 2009a and Stratix IV GX Development kit.

I have created the following scheme in Matlab: see image myhil_1.jpg.

And all works!

Then I have created the following scheme: see image myhil_2.jpg.

The devboard gives out a incorrect signal.

I have done all too most for other development kit Cyclone III Starter kit. And all works!

What is a problem with Stratix IV GX Development kit?

PS: sorry for my english)

    I think DSP Builder 10.1 didn't work very well with combinatorial systems. Try adding a delay block in between your Input and Output blocks.

    I adding a delay block in between my Input and Output blocks. It does not work correct.

    I think DSP_Builder 11.0 solves my problem, but I have not license for Quartus 11.0.

    11.0 should have fixed the combinatorial problem. It also fixed a case where multiple devices were on the same JTAG chain. I don't know whether that board has that problem.
