As long as the IP core simulation involves the following steps, you should get it right.
1. Generate simulation model, testbench (or example design), and simulator setup script files.
2. Set up your simulator environment and any simulation scripts.
3. Compile simulation model libraries.
4. Run your simulator.
Those are top-level files, you need to add your own stimulus to it.
For bfm simulation, you can try out the design example below and the document below.
