Simulate Input through USB or Ethernet

Hello,

I am a student working on my CS degree. My group was given a project to start a design on a web-based FPGA laboratory, so that students could visit a website, upload their vhdl code and see the code running on the FPGA board.

To get further on this project, i'll need to somehow develop a software solution to manipulate inputs. For instance, simulating flipping SW0 through either USB or ethernet.

Could anybody point me in the right direction for this?

Thank you

    Why not through the JTAG interface?

    Using a SOPC system (I don't even think you need a NIOS processor) and the system console tools (http://www.altera.com/literature/ug/ug_system_console.pdf), you can control SOPC builder components from the PC using TCL scripts. Add PIO components to your SOPC system and you can directly read/write the values from the PC.

    It may seem overkill at first, but compared to a USB/Ethernet or even serial interface, you don't need to design your own communication protocol, and this solution is easy to scale.

    My understanding of your project is: You (will) have an embedded system# 1 that is connected to your network and runs a web server. You (will) have an embedded system# 2 that consists of an FPGA, maybe some memory, maybe some interfaces.# 1 can download the configuration data into# 2 and afterwards can stimulate several inputs of# 2. Is this correct?

    Yes, that is exactly right, Harald. Unfortunately I'm not having any luck using the system console tools...i try running the system-console command in the NIOS CLI, but it tells me that command does not exist.

    What version of Quartus and NIOS IDE do you have? The system console tools only exist since Quartus 8.0
