Yes, the Stratix® III Early Power Estimator (EPE) version 7.1 incorrectly models the power when using dynamic parallel on chip termination (OCT). The power model assumes the parallel OCT is always on, regardless of the value entered in the output enable percentage column. The power estimation will be larger than expected since the power calculation will include parallel OCT even when the output is driving. In Stratix III devices, parallel OCT is disabled when a bidirectional pin is performing output functions.
Version 7.2 of the Stratix III EPE uses the output enable percentage value when calculating the power consumed by parallel OCT for bidirectional pins.
