The adders are treated as functions of input transition rate (Tx) and output load capacitance (Cload) and greatly improve the absolute accuracy of the timing simulator as compared to using multipliers. A methodology for predicting the sensitivity of timing performance to variations in voltage and temperature is presented.","PeriodicalId":300310,"journal":{"name":"Proceedings.

The schematic library consists of parameterized blocks that model various algorithmic functions. A schematic description of a design is first mapped to an HDL (Hardware Description Language) description, which is then synthesized using an RTL (Register-Transfer Level) or a behavioral synthesis tool. The HDL description generated by this method is optimized, easy-to-read and suited for RTL and behavioral synthesis tools. The synthesis results presented for some examples demonstrate the advantages of this technique.","PeriodicalId":300310,"journal":{"name":"Proceedings.

A mapping decision is made by examining the complete design, If a complex cell in the middle of a design has many redundancies because of the boundary conditions (inputs or outputs of the complex cell are somwehow related) the Boolean equations for the complex cell are simplified and the cell is implemented from single-output Boolean gates. Otherwise, the complex cell from the library is retained.

The modeling process involves both model and model test development. Simulation is used to ensure model correctness. Being able to create HDL models of complex systems is imperative in designing today's systems, but model creation and validation is itself a complex task. Intelligent use of tools is necessary to simplify of this effort. Hardware description languages such as VHDL have a powerful set of constructs, but the modeler must keep in mind the model's application when coding it. Model test benches that can be reused throughout the design cycle and simulation efficiency are critical to effective model testing.","PeriodicalId":300310,"journal":{"name":"Proceedings.
