1. A method of simulating an information technology (IT) system to produce parametric data, the method comprising: translating specifications of the IT system from a first modeling language to a second modeling language, the translating of the specifications creating at least one gate that includes a start element, a buffer element, a count element, and a value; incorporating component constraints into the translated specifications; simulating operation of the IT system based on the translated specifications and the component constraints, wherein a request arrives at the start element, and as the requests are moved to the buffer element the value in the count element is incremented by one; and generating a report of parametric data based on the simulation.
