Co-calibrated™ Internal Ports
Internal ports are advantageous for connecting outside elements into an existing geometry during design, but are a frequent source of error in most simulators due to the non-physical discontinuities that may be inserted into the simulation results. Sonnet’s Co-calibrated ports solve this issue. Calibration group properties are designed to simultaneously de-embed any cocalibrated ports to reduce error. Sonnet’s process removes unintended discontinuities of the port allowing precision for any transition, connector, component, or measurement probe models to be added to the current simulation, resulting in Sparameter dynamic ranges that often meet or exceed 100dB. This also enables powerful circuit optimization techniques based on usage of specific internal connections to attach many small series and shunt tuning elements in a framework schematic simulator.
Adaptive Band Synthesis
Precision for any circuit analysis is achieved through Sonnet’s unique technique of Adaptive Band Synthesis (ABS). ABS runs a detailed frequency sweep which provides reliable results in the fraction of the time required by point-bypoint EM simulation, especially for bandwidths exceeding 100x. After the user sets a specific band of interest, Sonnet’s ABS adaptively selects the smallest number of discrete EM simulation samples possible, and provides a detailed broadband S-, Yor Z-parameter data sweep. Overall simulation time is cut dramatically while detailed spectral behavior is still calculated to extreme precision.
3D current reconstruction technique
Sonnet's suites of high-frequency electromagnetic (EM) Software are aimed at today's demanding design challenges involving predominantly planar (3D planar) circuits and antennas. Predominantly planar circuits include microstrip, stripline, coplanar waveguide, PCB (single and multiple layers) and combinations with vias, vertical metal sheets (z-directed strips), and any number of layers of metal traces embedded in stratified dielectric material.

Time and Frequency Domain Extraction Models
Sonnet’s analysis engine extracts electrical models suitable for use in both frequency and time domain circuit theory simulators. Extraction models available in Sonnet are:
- PI-network Spice model extraction: Fits a PI-model between each pair of circuit ports, including mutual inductances (k factor), for use in simple circuits and circuits where a PI-model applies (multiple frequencies).
- Broadband Spice network model extraction: Extracts a single Spice model to match EM project behavior over the full simulation band with no limit placed on the circuit size or configuration.
- Transmission Coupling Matrix models: Exports the RLGC parameters in a format compatible with the mtline component present in the Cadence® Spectre® simulator.
- S, Y and Z-parameter models: Available in Touchstone™ and Cadence formats.
Desktop Parallel Processing
Parallel processing takes a multicore x86 processor, and allows each of these cores to function like a separate 64-bit parallel processor to yield maximum processing efficiency. Sonnet’s analysis engine makes efficient use of parallel processing on up to 48 CPU cores. This results in up to N-fold speed improvement for N cores. For optimal results in time-critical design cycles, Sonnet’s advanced High Performance Solver engine in combination with the emCluster® feature yields maximum speed-up potential.
Using the patented Conformal Meshing technology, Sonnet simplifies the work and increases simulation speed of curved geometries and off-grid circuit elements, all while including built-in edge current consideration for high accuracy models. This reduces memory and time required as compared to rectangular and triangular meshing techniques, while avoiding error-prone iterative or sparse matrix techniques.
The Sonnet® Suites™ develop precise RF models (S-, Y-, Z-parameters or extracted SPICE model) for planar circuits and antennas. The software requires a physical description of your circuit (arbitrary layout and material properties for metal and dielectrics), and employs a rigorous Method-of-Moments EM analysis based on Maxwell's equations that includes all parasitic, cross-coupling, enclosure and package resonance effects.
Sonnet maintains a single, dedicated focus on providing the industry's most accurate and reliable high frequency planar EM software. Our aim is to make it easy for our customers to either develop and analyze designs within our software, or to incorporate our tools into their existing design processes and frameworks. Customers need never commit to a proprietary framework in order to get the best in planar EM analysis.
