Foundation F1.4 LogiBLOX: Invoking LogiBLOX through Foundation F1.4 for 4000XL designs uses 4000EX family.
Description
Invoking LogiBLOX through Foundation F1.4 for 4000XL designs the 4000EX family to be used. The following message is returned when the user attempts to change the family to 4000XL.
Warning: Changing your target family from xc4000ex to xc4000xl during a design cycle may result in incorrect simulation. Implementation STYLE specific to one target family may be changed for another during LogiBLOX expansion in NGDBuild. Do you want to proceed?
解决方案
The 4000EX and 4000XL architecture is the same, and Foundation designs use the same library for EX or XL designs, so either family can be used.
