hi.. 

there is some problem in simulating the design. I have added a FIR Filter in the design but it is not simulating and the error message of vsim 3033 is displayed in the prompt. 

may be some library need to be added. 

any help will be appreciated.

Generally this error is triggered if missing library or some instance missed to be compiled. Can you check with the user guide to double check on the required libraries for compilation?

By the way, if you are using Megawizard the core, normally at the last page of the Megawizard, it will tell the libraries required for simulating the core.
