Peripheral Support
This section lists changes to the peripherals that might have a significant effect on Nios II developers.
SOPC Builder PLL Component
The Quartus II software version 5.1 includes a new phase-locked loop (PLL) component for SOPC Builder which allows SOPC Builder systems to instantiate one or more PLLs inside the system module.
Peripherals Installed with the Quartus II Software
Starting with the Nios II Development Kit version 5.1 and the Quartus II software version 5.1, embedded peripherals for the Nios II processor are included in the Quartus II software. Previously, the peripherals were included with the Nios II development tools. This change does not impact functionality of the peripherals or existing designs.
JTAG UARTs with names other than "jtag_uart"
Resolved an issue that prevented the Nios II IDE software templates from automatically choosing the correct device for
stdiowhen JTAG UARTs were not named "jtag_uart" exactly.
DDR/DDR2 SDRAM Controller Version Upgrade
The hardware example designs for the Nios Development Board, Cyclone II Edition were updated to use DDR/DDR2 SDRAM Controller version 3.3.0. Make sure you have version 3.3.0 of the DDR/DDR2 SDRAM Controller installed on your computer to rebuild those examples.
