Cadence Simulation Technology for PCB Design The Allegro PSpice Simulator provides a full-featured analog simulator with support for digital elements to help solve virtually any design challenge— from high-frequency systems to low-power IC designs. The powerful simulation engine integrates easily with Cadence PCB schematic entry solutions, improving time to market and keeping operating costs in check. An interactive, easy-to-use graphical user interface provides complete control over the design process. Availability of resources such as models from many vendors, built-in mathematical functions, and behavioral modeling techniques make for an efficient design process. Advanced analysis features (Sensitivity, Monte Carlo, Smoke, parametric plotter, and an optimizer with multiple engines) are built on top of the simulator to improve design performance, cost-effetiveness, and reliability. The Allegro PSpice Simulator now offers the new Device Model Interface feature for automating the code generation for multilevel abstraction models written in C/C++, and SystemC ® , Verilog A-ADMS, and a set of behavioral analog devices and controlled sources. The products are tightly integrated with Cadence Allegro ® Design Entry HDL and Cadence OrCAD ® Capture / CIS. The simulation technology can also interface with MathWorks' MATLAB Simulink package in a powerful co-simulation environment (SLPS). (See Figure 1.) Benefits • Improves simulation times, reliability, and convergence on larger designs • Improves speed without loss of accuracy via integrated analog and event-driven digital simulations • Explores circuit behavior using basic DC, AC, noise, and transient analyses • Allows system-level interfaces to be tested with actual electrical designs using SLPS • Offers library selection of more than 33,000 analog and mixed-signal models • Allows for automatic identification of analog and digital signals and applies A-to-D and D-to-A interfaces • Explores design relationships with "what if" scenarios before committing to hardware • Maximizes circuit performance automatically using Optimizer • Identifies and simulates functional blocks of complex circuitry using mathematical expressions, functions, and behavioral devices • Determines which components are overstressed using Smoke analysis and by observing component yields using Monte Carlo analysis • Virtual prototyping leverages GUI-based code generation of mixed-signal system models written in C/C++ and SystemC, and compact models from Verilog A using Automatic Device Model Synthesizer can be easily used in the PSpice environment On larger designs especially, PCB design teams need fast and reliable simulation to achieve convergence. The Cadence ® Allegro ® PSpice ® Simulator provides simulation technology for PCB design that offers a single, unified design environment for both simulation and PCB design. With integrated analog and event-driven digital simulation, teams benefit from improved speed without sacrificing accuracy. Using advanced analysis capabilities, designers can automatically maximize the performance of circuits. Allegro PSpice Simulator A unified environment for PCB design, simulation, and analysis
