On page 2 of the GUI, the Programmable Empty Type calculation is incorrect for the "1_From_Empty" and "2_From_Empty" selections. These two selections should indicate a threshold near Empty (Empty is 0). However, the current calculation incorrectly displays"1_From_Full" or "2_From_Full".
To work around this problem, enter specific numbers into the text box rather than using the pre-computed fractions "1_From_Empty", or "2_From_Empty".
This issue will be fixed in FIFO Generator 1.1.
