Dr. Mühlhaus Consulting & Software GmbH is value added reseller for EMPIRE XPU and provides customized workflows, templates and automation for EM simulation of integrated circuits, modules and packages.

EMPIRE XPU is based on the powerful FDTD method, which has become an industry standard for RF EM simulation. Due to EMPIRE XPU’s unique adaptive on-the-fly code generation, it exhibits the fastest simulation engine known today.

EMPIRE XPU applications include RFIC layouts with very complex layouts and large polygon count (e.g. complex eWLP packages or analysis of filler structure effect), electrically large structures at mm-wave frequencies (e.g. on-chip antennas with lenses and environment) and other challing designs where other EM simulation tools hit the limits for memory requirement or simulation time.

For an example of EMPIRE XPU simulation speed for RFIC applications, see our antenna application note: IHP SG13S on-chip antenna at 240GHz

Faster on CPU than others using GPU acceleration

With its Just In Time (JIT) structure and processor adapted code generation, EMPIRE XPU fully exploits the processor architecture by using the second and third level cache for multiple time stepping and parallelization on all built-in cores.

Scalable simulation power

Depending on your simulation power needs, EMPIRE  XPU can be scaled from a single local solver to remote solver and simulation cluster. In addition, Empire also offers built-in support for batch simulation running on Amazon’s AWS cloud service.

The ideal EM solver for mixed planar + 3D work

With integrated 3D and 2D editors, EMPIRE XPU supports efficient modelling of mixed planar + 3D designs. Objects are grouped by logical layers that can provide material properties as well as z-position, thickness, geometry priority and other properties. Using predefined templates for your technology, this enables very fast and efficient modelling.

Efficient modelling, high simulation speed and accuracy make EMPIRE XPU an ideal choice for RFIC and package application.

Existing Ansys HFSS simulation models can be imported into EMPIRE XPU, keeping geometries and materials.
