Error reported by S-function 'mip_control' in Control Block

Hi,

on the road to learn dsp builder advance, I find an error in run simulation of demo_firi.

demo_firi is example of subchapter of manual "DSP builder advance blockset" : creating a new model from an existing dsp builder design example and changing the namespace.

After solved problems on signals block, i find error:

Error reported by S-function 'mip_control' in 'my_tutorial/Control':

Found bad parameter value for parameter busClockFreq. Expecting type Double but found value dspb_firi.ClockRate / 4.

I beg you to help me.
