4.5. Co-Simulation and Verification

Try these first

1. 1.

   What is co-simulation?

   Hint

   Think about why we need to simulate both analog and digital together.

2. 2.

   Name one tool used for co-simulation.

   Hint

   Consider popular tools in mixed signal design.

3. 3.

   What is the main benefit of co-simulation?

   • A. It simplifies digital design.
   • B. It allows checking both analog and digital interactions.
   • C. It eliminates the need for testing.

   Hint

   Remember why both domains need to be verified.

4. 4.

   True or False: Monte Carlo simulations help predict process variation impacts on digital components.

   • True
   • False

   Hint

   Think about where analog signals are affected.

5. 5.

   Design a testbench for a mixed signal application involving an ADC and a microcontroller. Specify the inputs, expected outputs, and how you would validate performance.

   Hint

   Think about how the ADC's output might be affected by the input signal's variations.

6. 6.

   Discuss the significance of real-time testing versus simulation for mixed signal designs. What might be some pros and cons of each method?

   Hint

   Consider the scenarios where each might excel or fail.
