verilog logarithm

I've a statement in verilog looking like integer level = log(N) (Where N is a parameter and level is to be determined) But I understand I cannot do complex math statements in verilog, so I'm wondering if there is an alternative solution to the above problem?

Any feedback appreciated!

If it is a logarithm base 2 you are trying to do, you can use the built-in function $clog2().
