ANSYS HFSS Now Includes Circuit Simulation

ANSYS HFSS users can reduce design time and cost with the linear circuit simulation included with the latest version of the software, the company says. New HFSS product options for radio frequency (RF) and signal integrity (SI) analyses are also available.

The latest version of HFSS with circuit simulation combines “the accuracy of electromagnetic analysis with the speed and capacity of circuit simulation, providing a comprehensive systems-level view of the design,” the company said in a press release.

“It’s important for our customers to quickly analyze the full electromagnetic system including circuit level components and high-fidelity electronic models,” said Larry Williams, director of product management at ANSYS. “This product upgrade, coupled with our recent ANSYS SIwave product announcement, underscores our vision to deliver a seamless end-to-end simulation workflow and a simulation-driven product development approach to product design to our customers.”

Combining HFSS with circuit simulation is beneficial for complex RF, microwave, and electronics design because engineering teams can study multiple results in larger systems, expanding the size and scope of designs, the company says. Additionally, the software supports comprehensive SI design by allowing cascading transmission lines, connectors, printed circuit boards, sockets and IC package interconnects. The additional HFSS RF and SI product options provide more advanced circuit simulation analysis with specific capabilities targeting applications in RF/microwave engineering and high-performance electronics design.

The product includes linear circuit with integrated ANSYS Optimetrics for full system design to complement its traditional 3D and recently introduced 3D layout interfaces and 2.5D method of moments solver.

When combined with HFSS, the new ANSYS RF Option delivers a high-performance RF simulation flow including harmonic balance circuit simulation for non-linear microwave circuit analysis, filter synthesis and DC, transient, oscillator, load-pull and envelope circuit analysis engines.

The new ANSYS SI Option for HFSS provides a component-to-system simulation solution for signal and power integrity. It includes DC and transient circuit analysis, IBIS-AMI modeling, statistical eye analysis, Synopsys HSPICE simulation support, and the HFSS 3D transient finite element simulation engine for time-domain reflectometry (TDR) and visualization of 3D electromagnetic fields.
