Description
Yes, there is a problem with the IBIS model generation in the Quartus® II software versions 11.0 and 11.0SP1 for dual purpose configuration pins in Cyclone® III devices. The models for these pins will be assigned a drive strength of 16mA, but they are actually configured with the default drive strength of 8mA as shown in the Pin Planner. This only affects the 2.5V LVTTL/LVCMOS I/O standards, no other standards are affected by this issue.
Resolution
This issue is fixed in the Quartus II software version 11.1.
