June 18, 2024: The content below helps navigate the new features in this release. A full list of updates is available in the Reference Manual's Appendix.

XF 7.11.0 upgrades several third-party libraries, adding support for Linux RHEL8 and dropping support for RHEL6, and requiring CUDA 11.4 for use with GPU acceleration. XF 7.11.0 upgrades FLEXlm licensing libraries to version v11.19.1-TRL from v11.16.2-TRL. Customers using a floating license must update their floating license server.

Schematic Optimization on $\epsilon_s$

The schematic editor includes an optimization algorithm for determining component values. Users specify allowable component values and design goals before kicking off the optimizer. Metrics such as system efficiency, delivered power, and reflection coefficient can be specified as design goals.

Additionally, the optimization algorithm is available in the analysis workbench where users can switch between optimization and manual tuning sliders.

Schematic Subcircuits

XF's schematic editor now supports subcircuits with a user defined number of terminals and properties. Contents of the subcircuit are defined with built-in component types–capacitor, inductor, phase shifters–and imported data types–SnP files. Subcircuit's scripted properties allow extensive flexibility and enable impedance tuners with tune codes for cellular applications and repetitive matching networks in MRI applications.

A custom symbol can be applied to subcircuits.

Active S-Parameters

The active S-parameters macro provides output for phased array and active antenna applications.

HAC 2019

The HAC2019 macro enables users to post-process E-field results in compliance with the 2019 standard. The macro utilizes the existing HAC sensor to specify the location where electric-fields are computed and view the electric-field distribution through the specified plane.

IEC/IEEE Standards

XF 7.11.0 is compliant with and passes all tests outlined in the international standards determined by the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE).

Additional Capabilities

This version introduces over 50 usability, performance, scripting, and other updates.
