Thanks for the report.
PLL calculation is not yet described properly on the website. But the dialog should be user friendly. Here is a piece of information:
PLL parameters are computed automatically by the blockset. You have to provide only the quartz used and the desired MIPS to reach. The blockset will provide you with the closest solution possible respecting the many constraints of the PLL circuit.
On the version 0.94c, a bug makes the calculation unworkable as it is describe in the post above.
The problem is now resolved on the version 0.94d.
I couldn't test it completely; fell free to report what's going on...
