Obtaining Functionally Equivalent Simulations using VHDL and a Time-Shift Transformation

  title={Obtaining Functionally Equivalent Simulations using VHDL and a Time-Shift Transformation},
  author={Frank Vahid and Daniel Gajski},
VHDL and other hardware description languages have become popular as system speci cation languages in top-down design. However, their constructs do not support the behavioral speci cation of embedded systems. We introduce a new conceptual design model, called Program-State Machines, that caters to embedded systems. We then describe the SpecCharts language, an extended version of VHDL, which supports capture of this design model. In conjunction with a translator to VHDL, SpecCharts can be easily… CONTINUE READING
