Abstract

In this paper we present a tool to assist in teaching top-down and bottom-up analysis algorithms. The tool provides simulation for the following analysis algorithms: LL, SLR, LALR and LR. During the simulation the student can simultaneously see the pending input, the analysis stack and tables, the generated output and the parse tree.
