SOPC Builder

This section documents changes to SOPC Builder.

• Fixed issue where SOPC Builder tried to override non-editable parameters during component instantiation
• Added support for the "resetrequest" port on slave components

Peripheral Support

This section documents changes to the hardware peripherals included in the Nios^® II Development Kit.

The LAN91C111 SOPC Builder Component was modified to meet timing to the LAN91C111 device per its documentation whether a microprocessor or DMA is used to interface to the device. If you have an older version of the LAN91C111 Component in your design, you must remove the old component, re-add the new LAN91C111 Component in SOPC Builder, re-generate the system, and re-compile in Quartus II software.

Cyclone II example designs were updated to use DDR/DDR2 SDRAM Controller version 3.2.1. Ensure that you have version 3.2.1 of the DDR/DDR2 SDRAM Controller installed on your machine.

• Fixed a VHDL problem relating to the SSRAM controller's read latency in simulation.
• Fixed a potential bus contention issue with the SSRAM controller when read latency is set to 1.

• Fixed an issue relating to initialization of the DMA controller when the data width exceeds 32 bits.
