Running IIROrder2 demo

[Altera_Forum]

Hi dears, 

 I need your urgent help please. I'm trying to run IIROrder2 module which is in the Demos folder in the examples of DSP Builder, but the following error appears:   Error evaluating 'InitFcn' callback of block_diagram 'topiir'. Undefined variable "com" or class "com.altera.dspbuilder.simulation.Cache.createModel".   Thanks.

This means DSP Builder is likely not installed properly. 

 Try re-installing.

Thanks for your reply. 

 I do so, I re-installed it but same error appers.   I use Win7 64-bit and I install matlab 2010a 64-bit , and Quartus II 7.2, and DSP Builder 10.1.   Are there any thing may affect running the module?   Thanks alot.

DSP Builder 10.1 does not support 64-bit MATLAB. You need to install the 32-bit version of MATLAB.

In addition you can't use DSP Builder 10.1 in conjunction with Quartus II 7.2.

Thanks. 

 You mean that I can't use version 7.2 of Quartus II , what should it be plz?

You should use Quartus 10.1. DSP Builder is installed as part of Quartus. It is only compatible with a Quartus that has the same version number.
