Operating System: Win7 bitDevelopment Environment: Quartus II 14.0 (64-bit) + Nios II EDS 14.0When using Quartus, sometimes due to backup considerations, or download other people's hardware engineering from the Internet, the hardware engineering catalog will change, resulting in Nios project can not find sopcinfo files, so that the next software development can not be done. The cumbersome approach is to cre

Two-way foot, when it is output foot, is open drain. When the pin is output as a status, it is set to low level before and during the configuration. Once the configuration data is received and there are no errors, the initialization cycle starts and the Conf_done is released. When entering a pin as a state, when all da

I am sharing my personal experience here. I have been using Quartus II 9.1 and niosii IDE 9.1 on Windows 7 since they were released. now, I am using Quartus II 9.1 SP2 and NiO II IDE 9.1 SP2.A lot of users were asking questions the compatibility of these softwares on Windows 7. quartus II 9.1 and its FPGA builder seem to work fine on Windows 7 since the first day they are installed. it is the nio ii ide 9.1 that really bothered me. most of the time when you build a project, it will report ErrorM

This paper records some problems encountered in the use of Nios and related causes analysis and solutions, make a summary convenient for later review. I also hope to help the siege lions with the same problems.

PRJ) 2 Qsys Hardware System Setup Open Qsys in Quartus II: Opening the Qsys interface discovers that there is already a clk_0 under system contents as shown in. To build a minimal system, you must also add some necessary components, such as Nios II processors, JTAG, Onchip_ram, SystemID, and so on. Add Jtag: Add Nios II Processor Add Onchip_ram A

Several settings to note in the software after switching the main memory of the Nios II CPUSometimes, we may face a situation where:1. We create a SOPC system and set the reset address and the exception address of Nios II in the Qsys to point to SRAM;2. We have created the correct Nios II software engineering and are able to operate properly3. Due to a demand (su

Sof, POF, and elf Sof = FPGA internal SRAM configuration data, which can be downloaded through JTAG. After downloading, the hardware functions of FPGA are implemented. After power loss, the hardware becomes volatile.POF = configure the flash data of the device and download it to the configuration device in as mode. When the device powers down and is powered on again, FPGA will automatically read the configuration data from the configuration device, and then configure the SRAM inside the FPGA, i

As for interrupts in Nios, interrupts are used when the 16c550 needs to be tested in a nios interrupt environment. Hardware: Add Hardware Pio in Nios, but enable interrupt function. As shown in the following: System is listed, the connection to PIO is not said. But be aware of two places: Edge type, IRQ type. The next step is software design: enable the corres
