Hi All,

I just got reply from Altera techinical support staff. He said that he is aware of this issue but this bug has not been fixed in 13.1.4. But the workaround is simple.

Every time you enter the frequency value in “Clock rate” and “Desired Output Frequency”, you have to hit an enter button of your keyboard.

For example:

1. Key in XX into “Clock Rate”, then hit “enter” key on your keyboard.

2. Key in XX into “Desired Output Frequency”, then hit “enter” key on your keyboard.

Cheers,

Lee
