General Description: In Project Navigator's "Sources" under the Project window, if I double-click on the .xco file for my Async FIFO core, CORE Generator opens with incorrect bounds for the Data Port Parameters. After this, I cannot get back to all available bounds for the core, as the lower bound of the FIFO depth is no longer available.
ソリューション
To work around this, you need to change the Input Data Width to another value, then change it back to your target value; the proper bounds for the FIFO depth will then be available.
This is a known issue in the software, and it is currently being investigated.
