fusesoc sim de0_nano fails

[berndca]

I'm trying to simulate de0_nano using the icarus simulator. I'm getting the following messages:

Please advise.
Thanks, Bernd

Not entirely sure, but I've seen people reporting similar problems quite recently. I think it could be that your Icarus version is too old. Which version are you using? Could you try to update it, or run with modelsim (by supplying --sim=modelsim after the sim command)

Good point. Failed with iverilog v0.9.7 installed with apt-get. Worked with v10.1 installed from github repo.
