The employment of Static2D/3D enables the developer of any type of digital circuits and high frequency analog circuits to make a first simulation of arbitrary connection structures on the circuit layout. This is made possible by using a Spice compatible analog simulator. The range of use includes telecommunications, information processing, medical technology as well as microsystem technology.

With Static2D/3D the modeling of transmission lines on printed circuit boards and integrated circuits is possible. The capacitance's, inductances and resistances per unit length on these transmission lines can be calculated two-dimensionally.

Also, you can define the substrate plane within the 2D cross section, for EMC of ICs. This special feature is used in the 2D EMC Simulation of ICs due to the conductivities potentially being different than zero. The propagation mode of the signals can change from the quasi TEM-mode to the so-called Slow-Wave Mode. This is because of the movable charges in the substrate which lead to a special mechanism of polarization: the substrate layer between the transmission lines (upper side) and the ground plane (lower side) act as a lossy capacitor with a very high permittivity. The number of substrates within one system cannot be greater than 2. Click here for an example image of an IC inductance calculation.

Furthermore line discontinuities which are included in the layout can be modelled and their capacitances and inductances can be calculated three-dimensionally. Static2D/3D distinguishes between numerous arbitrarily shaped discontinuities:

• corners
• bends
• steps
• deviations
• crosses
• pins
• vias

In addition Static2D can calculate wave impedances (mode impedances, mode admittances, mode velocities, mode runtimes, mode complex phases, potential mode shapes, current mode shapes - click on image to see modes of propagation with differing velocities).

Static2D/3D is able to be applied in different phases of the circuit development process. On the one hand consequences of possible negative effects (such as reflections caused by discontinuities or line cross-talk) can be foreseen while the layout is developed.

On the one hand the program looks at special line geometries, while at the same time it functions as a tool:

• to optimize the layout
• to place bus structures
• to specify driver and receiver circuits
• to place vias
• to simulate signal behaviour while variating the loading

The geometrical parameters of the structures to be analyzed can be specified by the user in a quick and simple way with the aid of an efficient user interface.

Arbitrary line arrangements can be set up from simple elements such as pins, single lines and vias while the combination of these separate geometrical structures to continuous lines automatically happens.

In addition it is possible to replace free space between lines with partial ground areas. Their geometrical dimensions are calculated on the given line geometries.

Typical of the efficient modeling and calculation methods of Static2D/3D are:

• especially quick calculation methods while maintaining a high degree of exactness
• ability to model complex circuits
• arbitrary geometry's of the copper on the layout (area fills)
• unlimited number of dielectric and metallic layers
• visualization of charge and current density distribution

An easy adaptation to the design environment and the demands of the user are made possible by the multiple output formats of Static2D/3D:

• Spice-equivalent circuit for arbitrary two- and three-dimensional geometry's
• Spice-equivalent circuit for general line systems (transmission lines)
• Support of Eldo-specific line system models
• (Lossy Wire) representation
• matrix representation for wave impedance Z
