Configurations aren't automatically applied to entities in Modelsim. If you are simulating a test bench, you need to instantiate the configuration rather than the entity. If you are instantiating a component, you can bind it to the configuration with a configuration specification in the architecture declarative region: 


for inst: my_comp
    use configuration work.cfg;

If you are simulating your entity directly (and possibly driving your own stimulus onto the pins), you need to simulate the configuration instead, e.g. 

vsim work.cfg

vs. 

vsim work.entity
