Description
The Quartus® II software versions earlier than 3.0 had a routing error which prevented successful read operations from the Remote Configuration shift register. This error caused the shift register output to be stuck at GND or VCC. Write operations to the shift register (updates to page & watchdog timer values, core-initiated reconfiguration) were unaffected by this error.
This problem is fixed beginning with the Quartus II software version 3.0 for all Stratix® devices.
