neoVAMS
About neoVAMS
neoVAMS is a high performance multi-partition analog solver extension/plug-in for industry standard SystemVerilog simulators. Simulation speedup is typically 20x-100x depending on design. Uses include:
- Enabling a low cost mixed-signal simulation/verification solution supporting Verilog-AMS and functional models
- Accelerating high cost high end simulation platforms used for large complex modules and SoCs incorporating Spice and AICMs
- Promoting re-use of module-level Verilog-AMS models at SoC level
Benefits include:
- Higher verification coverage as a result of increased testing
- Lower costs associated with model development and maintenance - fewer sets of models needed
- Lower costs associated with test development - less wait time in modify-simulate-debug cycle
- Faster late-stage detailed design-change validation - anything neoVAMS in a DUT will simulate super fast
Features
- High speed Verilog-AMS plug-in for SystemVerilog simulators
- Fast multi-instance analog solver supporting circuit partitioning, resulting in high simulation speed compared to conventional AMS solvers
- Solver boost (up to 2x) for circuits exhibiting a reasonable level of repetition (eg SMPS)
- Support for auto-inserted supply-sensitive Connect Modules when used with Cadence® Xcelium/Spectre
- Built-in Discrete Electrical Multi-Channel Analog Wires for use with functional analog models
- Real-time GUI-based profiler for identifying and fixing simulation-speed bottlenecks
- Compatible with Cadence® Xcelium, Modelsim/Questa-Intel® FPGA, Icarus Verilog; untested with Synopsys® VCS
Tool Flow for Complex Design Configurations
neoVAMS integrates neatly with Cadence® Xcelium/Spectre when design configurations include Spice-based views and require support for AICMs. The tool flow requires one simple additional step between "netlist" and "run":
- Netlist the design
- Auto-distribute Verilog-AMS cellviews between Spectre/Xcelium and neoVAMS as desired, and compile/add the neoVAMS cellviews
- Run the simulation
