How can I run TimeQuest with a 0.9 V core voltage setting for Stratix III low power devices?

The 0.9V core supply voltage is available for Stratix® III low-voltage devices (with an L ordering code suffix).

To set the core supply voltage in the Quartus® II software, follow these steps:

1. On the Assignments menu, click Settings
2. Under Operating Settings and Conditions, click Voltage
3. Select 0.9V for Core supply voltage

Run TimeQuest to view the results for the appropiate timing model. The following operating conditions are available in TimeQuest after you compile your design with the 0.9-V core voltage setting:

• Slow 900 mV 85°C model
• Slow 900 mV 0°C model
• Fast 900 mV 0°C model
