W2303 Verilog-A Elements

Brochures

 Verilog-A custom non-linear models can be developed and used in all ADS circuit simulators

The W2303 Verilog-A element is an analog behavioral modeling and simulation environments for the Advanced Design System (ADS). ADS is the flagship product from Keysight Technologies’ EEsof EDA, the technology and innovation leader in high-frequency mixed-signal electronic design automation (EDA).

ADS is the only design simulation platform that enables the co-design of IC, package, and board in high-frequency and high-speed applications. It seamlessly integrates system, circuit, and full 3D electromagnetic simulation with Keysight Technologies’ test instrumentation, resulting in repeatable, first-pass electronic design success.

The W2303 Verilog-A Element enables analog behavioral modeling with the industry standard Verilog-A language within ADS. Used for applications ranging from transistors to MEMs, the Verilog-A models are compiled for speed and can be simulated and optimized with any of the time-, frequency- or envelope-domain system and circuit simulators in ADS.

Verilog-A supports so-called multi-discipline modeling, where the through and across variables need not be the familiar current and voltage variable supported by SPICE netlist syntax. In addition to that traditional electrical discipline, it supports magnetic, thermal, and kinematic natures and disciplines. The user can define additional discipline. Bilateral transducers between disciplines (such as an electric motor with back EMF and torque) can be modeled easily.

The user-defined models using standard Verilog-A equation constructs are intelligently compiled in ADS to use the fast and robust convergence algorithms already engineered for built-in ADS models, thus eliminating the special formulation of behavioral equations for specific simulators to converge. A comprehensive library of valuable Verilog-A source codes are supplied for new and built-in ADS models to allow fast new model development or to efficiently customize the underlying model equations. Customized Verilog-A models can contain parameters that can be extracted from measurements in Keysight’s powerful IC-CAP (Integrated Circuit Characterization and Analysis Program) parameter extraction and device modeling software environment that also controls instrumentation and probe stations

The W2303 Verilog-A Elements includes:

  • Support for industry-standard Verilog-A model development in ADS, with run-time speed and convergence comparable to built-in ADS models.
  • Simulation and optimization in ADS time-, frequency- and envelope-domain system and circuit simulators, with full access to powerful internal convergence algorithms.
  • At least 10x less lines of code compared with C-language-based models.
  • Fully portable model development for use in all Verilog-A compatible simulators, distributable through design kits.
  • Verilog-A model parameters extracted from measurements in the Keysight ICCAP device modeling environment.
  • Verilog-A source codes for new models.
  • Verilog-A Source codes for built-in devices.
