[**[Hold for ISE 10.1 SP 3]]
Within certain range selections for Write Depth and Write Width, the Block Memory Generator core customization GUI can crash.
For example, the issue occurs in the following situations:
- When Port A Write Depth A = 9011200, the above error occurs in the GUI console and the GUI crashes if any value between 239 and 470 is placed in the Write Width A text box and all other parameters are left as default values.
- If Port A Write Depth = 4505600, the above error occurs in the GUI console and a range from 477 to 953 in Write Width A causes the GUI to crash with all other parameters set to the default.
This issue has been fixed in ISE 10.1 IP Update 3.
