Hi @Liyen,
Good to know that the complier gcc version issues has been fixed.
For the modelsim issues we do have a better experiences team supporting that as link below:
- https://community.intel.com/t5/Intel-FPGA-Software-Installation/bd-p/fpga-software-installation-licensing
Perhaps if you can provide more details on the errors and logs that would be better for us to dig deeper into the strange issues.
As for the example project for HLS, upon installation there will be included in the following path below:
- <quartus_installdir>/hls/examples/<design_example_name>
Hope that clarify
Best Wishes
BB
