The UML diagram to VHDL code transformation based on MDA methodology

Abstract

The Model Driven Architecture (MDA) methodology requires several intelligent operation stages, such as the computation independent model transformation (CIMT), the platform independent model transformation (PIMT), and the platform specific model transformation (PSMT), to progressively transform an abstract model to a physical system. The special Unified Modeling Language (UML) or StarUML is the core tool of CIMT that models a digital system in a diagram paradigm. PIMT uses the Python language with minidom object to perform a series translation from UML diagram to VHSIC Hardware Description Language (VHDL) code. Finally, the PSMT imports an os object to Python for running a series of synthesis command script to get bit stream that is finally downloaded into FPGA device to complete the realization of the digital logic circuit. © 2013 Springer-Verlag Berlin Heidelberg.
