Questa warning vsim-3473 Component instance is not bound.
I am using Quartus Prime Pro 25.3 and Questa Altera Starter FPGA Edition-64 2025.2. I am trying to simulate a design with numerous Altera IP. I get the "not bound" warning for the many, possibly all, of the Altera IP. I have searched online and this forum. I see the same problem identified with ModelSim. I could not find anything specifically Questa. I have tried various posted solutions but have had no success. I generated simulation models for all IP in Quartus. For one of the IP, I tried creating the simulation model in VHDL and Verilog and tried Traditional and Qrun QuestSim flow selection. I checked the QuestaSim box for which simulator script will be generated. I found some solutions talking about using the command line in Questa. I very much prefer to remain in in the GUI for all commands.

Hi sselhorst
Have you tried the automating simulation with the run simulation feature?The official user guide is available here:
https://docs.altera.com/r/docs/730191/25.3/questa-edition-simulation-user-guide/automating-simulation-with-the-run-simulation-feature
This flow will automatically:-Generate the required simulation setup files
-Compile the Altera IP simulation models
-Compile the design files
-Launch Questa
If the issue still persists, could you please share the design .qar file (Project → Archive Project) so that we can investigate further?
Regards,
