VHDL Auto-Generation for Software Defined Radios
This paper describes a case study examining two distinct design processes for implementation of FPGA-based
software defined radio subsystems. We compare a traditional RTL design approach with a model-based design
flow involving automatic code generation using System Generator. Both design processes were applied to the
development of a common SATCOM waveform: Mil-Std-188-165a. Results indicate a 10:1 improvement in
development efficiency using System Generator, based on quantitative comparison of the time consumed in
developing system simulations, algorithm documentation, code design and debugging, hardware
implementation, and algorithm verification. The time savings associated with performance analysis using
hardware co-simulation is alsoassessed.
