Unable to simulate de0_nano

[jeebujacob]

Hello , i m a newbie to openrisc system, got an error trying to simulate the de0_nano system.

Reference: jeebu@jeebu:~/openrisc/orpsoc-build$ fusesoc sim --sim=icarus de0_nano

Compiling /home/jeebu/openrisc/orpsoc-build/build/de0_nano/src/elf-loader/elf-loader.c... Compiling /home/jeebu/openrisc/orpsoc-build/build/de0_nano/src/elf-loader/vpi_wrapper.c... /usr/bin/iverilog-vpi: 1 file(s) failed to compile. ERROR: Failed to build simulation model ERROR: Failed to compile VPI library elf-loader

Thanks in advance.

regards Jeebu

Hi,

Not sure why this is happening, but let's find out :) Which version of FuseSoC are you using? I'm also very interested in seeing what you have in build/de0_nano/sim-icarus/jtag_vpi.log. Could you send over the contents of that file?

As a general advice, you should rerun the simulation with the --force parameter (fusesoc sim --force --sim=icarus de0_nano) to make sure that there aren't any old parts left. It's not very intuitive, I know that :) You could also try to clean out the cache manually. Just delete everything under ~/.cache/fusesoc

Thanks a lot Olof, the last error was due to the absence of gelf.h header. But once the header was in place, and simulation was forced, it came up with a syntax error

Dont understand why the syntax is wrong. I m attaching a snap of the code, highlighting the 56th line.

Attaching build/de0_nano/sim-icarus/jtag_vpi.log file contents

Hi.

I've been working on adding simulation support for de0_nano the last couple of days. It's working now, but I will need some more time to clean things up

[jeebujacob]

Forgot to mention..... the last syntactical mistake was because of the version of iverilog(0.9.6 needed).

Hi, Seems like it was quite a while since I last looked at the open issues. Was this ever resolved?

[olofk]

Closing this now due to inactivity. Simulations also work fine for me on de0 nano
