For more information about the battery specifications, refer to the
Data Sheet
Cyclone III LS devices are SRAM-based devices. To provide design security,
Cyclone III LS devices require a 256-bit volatile key for configuration bitstream
encryption.
The Cyclone III LS design security feature provides routing architecture optimization
for design separation flow with the Quartus II software. Design separation flow
achieves both physical and functional isolation between design partitions.
For more information about the design separation flow, refer to
Design Separation Flow.
You can carry out secure configuration in Steps 1–3, as shown in
1. Generate the encryption key programming file and encrypt the configuration data.
2. Program the volatile key into the Cyclone III LS device.
3. Configure the Cyclone III LS device.
Figure 9–31. Cyclone III LS Secure Configuration Flow
Note to
(1) Step 1, Step 2, and Step 3 correspond to the procedure detailed in
The Quartus II configuration software uses the user-defined 256-bit volatile keys
to generate a key programming file and an encrypted configuration file. The
encrypted configuration file is stored in an external memory, such as a flash
memory or a configuration device.
Program the user-defined 256-bit volatile keys into the Cyclone III LS device
through the JTAG interface.
At system power-up, the external memory device sends the encrypted
configuration file to the Cyclone III LS device.
