Mixed-Signal Blockset™ provides models of components and impairments, analysis tools, and test benches for designing and verifying mixed-signal integrated circuits (ICs).
You can model PLLs, data converters, and other systems at different levels of abstraction. These models can be used to simulate mixed-signal components together with complex DSP algorithms and control logic. You can customize models to include impairments such as noise, nonlinearity, jitter, and quantization effects. Rapid system-level simulation using variable-step Simulink® solvers lets you debug the implementation and identify design flaws without simulating the IC at the transistor level.
With the Mixed-Signal Analyzer app you can analyze, identify trends in, and visualize mixed-signal data. The Cadence® Virtuoso ADE MATLAB Integration option lets you import databases of circuit-level simulation results into MATLAB®. Alternatively, you can import a SPICE netlist and create or modify a linear, time-invariant circuit with parasitic elements extracted from the IC design. The blockset provides analysis functions for post-processing simulation results to verify specifications, fit characteristics, and report measurements.
Phase-Locked Loop Design
Design and simulate phase-locked loops (PLLs) at the system level. Typical architectures include integer-N PLLs with single or dual modulus prescalers and fractional-N PLLs with accumulators or delta-sigma modulators. Verify and visualize the open-loop and closed-loop responses of your designs.
Design your mixed-signal system using building blocks such as charge pumps, loop filters, phase frequency detectors (PFDs), voltage-controlled oscillators (VCOs), clock dividers, and sampling clock sources, among others. You can further refine analog models at a lower abstraction level with Simscape Electrical™.
“In the past, we didn’t know how well our designs would handle jitter until we tested them on the chip. Now that we run system-level simulations with discrete- and continuous-time models in Simulink, we have confidence that when we tape out a chip it’s going to work.”Henrik Holm Johansen, GN Hearing
