1. Mixed-Signal Co-Simulation: Run full-chip or block-level simulations combining analog solvers and digital engines using tools such as Cadence AMS Designer/Xcelium or Synopsys VCS.
2. Behavioral Modeling: Develop high-level analog behavioral models using Verilog-AMS, Verilog, or SystemVerilog Real Number Modeling (RNM/wreal).
3. Testbench Development: Build metric-driven verification environments using System Verilog and UVM-AMS methodologies.
4. Debugging and Coverage: Analyze analog and digital interface issues, waveform anomalies, simulation convergence failures, and drive functional coverage closure.
5. Automation: Develop scripts in Python, Perl, or Tcl to automate verification flows, regression management, and reporting.
6. Model vs. Schematic Verification: Develop and execute verification plans to ensure functional equivalence between high-level behavioral models and transistor-level schematics.
7. Mixed-Mode Configuration Management:
Configure and execute mixed-mode simulations where selected blocks run at schematic/SPICE level while the remaining design runs using behavioral models.
