In the following sections, we will discuss some of the key features of zeland ie3d v15 that make it a powerful and versatile EM simulation solution.
Automatic Geometry to IE3D Flow (AGIF)
One of the unique features of zeland ie3d v15 is the automatic geometry to IE3D flow (AGIF), which simplifies the EDA flow by allowing users to create 3D EM models from different platforms such as GDSII, Cadence Virtuoso, Cadence Allegro, and Microwave Office. AGIF converts the 2D layout data into 3D IE3D models automatically, without requiring manual intervention or editing. AGIF also preserves the design hierarchy and parameters from the original platform, so that users can easily modify and update their designs in IE3D.
AGIF enables users to perform full-wave EM simulation and verification at any stage of their design process, from schematic to layout to post-layout. AGIF also supports bi-directional data exchange between IE3D and other platforms, so that users can import and export their designs as needed. AGIF eliminates the need for tedious and error-prone manual translation of design data, and ensures consistency and accuracy across different design domains.
Distributed Simulation and Optimization
Another feature of zeland ie3d v15 that enhances its scalability and performance is the distributed simulation and optimization capability. This feature enables users to run parallel simulations and optimizations on multiple machines for faster turnaround time and higher capacity. Users can distribute their simulations and optimizations across a network of computers, either locally or remotely, using a simple graphical user interface (GUI). Users can also monitor and control their distributed jobs from a central console.
Distributed simulation and optimization allows users to take advantage of the computing resources available in their environment, such as multi-core processors, clusters, grids, or clouds. Users can also balance their workload among different machines according to their availability and performance. Distributed simulation and optimization reduces the run-time and memory requirements of large-scale EM problems, and enables users to explore more design alternatives in less time.
Advanced Modeling and Post-Processing Capabilities
Zeland ie3d v15 also supports various advanced modeling and post-processing capabilities that enable users to create realistic and accurate EM models and analyze their results in depth. Some of these capabilities are:
Parameterized cells: Users can create parameterized cells that represent common or repeated structures in their designs, such as vias, bond wires, spiral inductors, etc. Parameterized cells can be easily inserted, modified, or deleted in IE3D models using parameters such as position, size, shape, material, etc.
Ports: Users can define ports on their IE3D models to specify the excitation sources or measurement points for their simulations. Ports can be either lumped or distributed, depending on the type of connection between the model and the external circuit. Ports can also be assigned impedance values or de-embedding networks for accurate characterization of device performance.
Vias: Users can model vias in their IE3D models to account for the effects of vertical interconnects in their designs. Vias can be either cylindrical or rectangular, and can have different cross-sectional shapes, such as circular, elliptical, square, or polygonal. Vias can also have different types of terminations, such as open, short, or matched.
Substrates: Users can define substrates in their IE3D models to represent the dielectric layers and ground planes in their designs. Substrates can have different thicknesses, permittivities, conductivities, and loss tangents. Substrates can also be stacked or layered to form multilayer structures.
Frequency-dependent materials: Users can model frequency-dependent materials in their IE3D models to capture the dispersive effects of some materials at high frequencies. Frequency-dependent materials can be defined using either analytical models or tabulated data. Frequency-dependent materials can be assigned to any part of the IE3D model, such as segments, cells, ports, vias, or substrates.
S-parameters: Users can calculate the S-parameters of their IE3D models to characterize the scattering behavior of their devices. S-parameters can be computed for any number of ports and frequencies, and can be displayed in various formats, such as magnitude, phase, real, imaginary, Smith chart, etc. S-parameters can also be exported to other EDA tools for further analysis or synthesis.
Currents: Users can visualize the currents on their IE3D models to understand the current distribution and flow on their devices. Currents can be displayed in various modes, such as vector, contour, color map, etc. Currents can also be animated to show the time-varying behavior of the devices.
Fields: Users can visualize the fields around their IE3D models to understand the field distribution and radiation from their devices. Fields can be displayed in various modes, such as vector, contour, color map, etc. Fields can also be animated to show the time-varying behavior of the devices.
Radiation patterns: Users can calculate the radiation patterns of their IE3D models to characterize the radiation performance of their antennas or radiating devices. Radiation patterns can be computed for any direction and polarization, and can be displayed in various formats, such as polar, rectangular, 3D surface, etc. Radiation patterns can also be exported to other EDA tools for further analysis or synthesis.
