Static analysis can be used to determine safe estimates of Worst Case Execution Time. However, overestimation of the number of loop iterations, particularly in nested loops, can result in substantial pessimism in the overall estimate. This paper presents a method of determining exact parametric values of the number of loop iterations for a particular class of arbitrarily deeply nested loops. It is proven that values are guaranteed to be correct using information obtainable from a finite and quantifiable number of program traces. Using the results of this proof, a tool is constructed and its scalability assessed.
