Remcom announces circuit cosimulation in XFdtd

Dec. 18, 2017

State College, PA. Remcom has announced circuit cosimulation and expanded signal integrity capabilities in the latest update to its XFdtd 3D electromagnetic simulation software.

Circuit co-simulation facilitates a more realistic analysis of device performance by including imported circuit components within the electromagnetic simulation. The schematic for a desired component may be imported into XF via a netlist file, with support for Spice elements such as resistors, capacitors, inductors, coupled inductors, and subcircuits. Netlist components can also be assigned as a matching circuit embedded within a feed, simplifying matching network design.

This release also introduces a nodal waveguide interface with enhanced options for computing S-parameters. A user-defined reference impedance enables renormalized S-parameters to be computed for transmission lines that would typically display an impedance mismatch. A nodal excitation is also available for simulations that do not require S-parameters to be collected.
