how to simulate NIOS II generated in Qsys_Pro v17.0

Thanks for you reply.

I'm using Quartus Prime Pro V17.0, Qsys_pro v17.0, cadence incisiv v13.20.

I don't think tool version is causing problem, I can use Quartus v13.1 to generate NIOS core and simulate it without any problem.

Now I need to migrate to Arria 10, so when I generate NISO in Qsys_Pro v17, it only gives me encrypted file <file_name>.vo, below is part of the .vo file.

`pragma protect begin_protected

`pragma protect version=1

`pragma protect author="Intel Corporation"

`pragma protect encrypt_agent="Quartus Prime Pro Software"

`pragma protect encrypt_agent_info="17.0"

`pragma protect key_keyowner="Aldec"

`pragma protect key_method="rsa"

`pragma protect key_keyname="ALDEC15_001"

`pragma protect encoding=(enctype = "base64", line_length = 76, bytes = 256)

`pragma protect key_block
