Hello, I am using cycloneIV device for a simple project to explore tool using web version. and ended up with following error at simulation.

Ok, so the issue with the Cyclone IV E IOBUF sim model is resolved. This error is due to the sim library name. What I had provided earlier for the 220 Model lib is incorrect. You can remove the -L 220model_ver and then re-run the simulation. It should work this time.
