The use of isolated design tools constrains engineers to follow separate design paths for analog and digital design. This tool isolation delays the discovery of errors at the analog-digital interface and makes the evaluation of trade-offs between analog and digital designs difficult for engineers.

Simulate, Test, and Verify Mixed-Signal Systems in the Same Environment

The advanced simulation engine in Simulink enables you to simulate analog and digital designs together in the same model and thoroughly test the analog-digital interface early in the design process. The cosimulation links between MATLAB and Simulink and third-party design tools, such as Cadence Virtuoso AMS Designer and Mentor Graphics ModelSim, further enable you to verify SPICE or HDL models in the same analog and digital design environment.

Evaluate Analog and Digital Design Tradeoffs Using Advanced Techniques

The intuitive combination of analog and digital designs in the same model lets you design across domains and use advanced techniques such as digital predistortion and digital feedback. With Simulink, you can:

• Improve the operation of analog power amplifiers using digital predistortion
• Replace analog components in the feedback loop with digital equivalents using digital feedback methods
