How to simulate the FPGA neural network in Altera

I have converted yesterday my Simulink design to Verilog file foe about 8000 lines. Is it incorrect? It even automatically launched in Model sim but it said there is no design files. And to add wave window I do not know through menu. Anyway what such quadratic shaped signals could show in HDL simulation--could it show the decreasing of signal as it is in Simulink?

I appeciate your fixdt conversion but I do not understand how do you do it. You apply it to adders, integartor, constants, gain. But why some is 1,12,24 but other 1,6,12--what it means? If so could I now correctly convert it to HDL. And one more note--the if-else blcok should be replaced by two switch blocks--1-3 input like.

And what about DSP--should I also convert to fixdt for it? Where I could find fine tutorial for it?

And yet the question again--how can I note the Matlab path for Dsp Blockset?

Now I have Matlab2009a and it has more opportunities, such as fixdt, Simulink Fixed Point (with reference to Block Libarry), Matlab fixed-point but just help
