7. HyperLynx

Innoveda, Inc

Marlborough, MA

Phone: (800) 873-8439

Software: HyperSuite EXT

Description: HyperSuite includes LineSim (Pre-Layout signal integrity simulation), BoardSim (Post-Layout signal integrity simulation), plus EMC and Crosstalk Analysis. With the HyperSuite, users can address high-speed PCB problems throughout the design cycle, beginning at the earliest, architectural stages and moving through post-layout verification.

LineSim is a pre-layout signal integrity analysis tool. It provides the capability to investigate and plan for signal-integrity issues in the pre-routing design stages prior to PCB layout. Hypothetical interconnect scenarios may be entered in a “cell-based” schematic editor. Then, a detailed signal-integrity analysis may be performed. Waveforms are displayed in an oscilloscope viewer. The EMC analysis option to LineSim adds a spectrum analyzer that predicts radiated emissions from pre-layout net topologies. The predicted radiation levels can be compared at every frequency to government or user-defined limits.

BoardSim is a post-layout signal-integrity analysis tool. It reads the information in an actual routed PCB layout and allows a designer to perform detailed signal integrity analysis based on the exact routing of a particular layout. For every net that is simulated, BoardSim automatically constructs an electromagnetic simulation model on a segment-by-segment and via-by-via basis. Analysis is available in both “batch” and interactive modes. BoardSim's EMC option is unique for post-layout verification in that it can predict radiation levels not only from PCB traces, but also from component packages. It does this without requiring any modeling information about the components' packages.

8. Pacific ESI

Artarmon, Australia

Phone: (02) 9906-3377

Software: PAM CEM 2000

Description: This software was developed to perform realistic and predictive EMC simulations for industries such as aeronautics, telecommunications, electronics, and automotive. It is designed to simulate EMC lab testing, ranging from EMI caused by internal equipment wiring up to susceptibility or immunity of on-board equipment to external aggressions, as well as electromagnetic radiation of large harness systems towards the external environment (electromagnetic pollution). Capabilities include: Signal propagation on circuit boards and along interconnects: signal integrity, cross-talk, reflection and transmission analysis, s-parameter extraction; Electromagnetic compatibility and interference (EMC/EMI) analysis; Near to far field transform for radiation and EMC / EMI applications; Total field / scattered field zones for external wave sources; Electric, magnetic, and current density field sources; Built-in lumped elements including resistors, capacitors, inductors and voltage sources.

9. Quantic EMC Inc.

Manitoba, Canada

Phone: (204) 942-4000

Software: the Quantic Engine - includes “Omega Plus” for signal integrity and EMC simulation, and “Compliance” for system level EMC simulation of PC boards, enclosures, and cables.

Description: Use “Omega PLUS” for screening PCB layouts for crosstalk, ringing, time delays, overshoot, undershoot, settling time and noise margin violations. Locate high-emission regions and identify the nets that cause EMC violations. Simulate two-sided boards and multi-layer boards with split power and ground planes. “Compliance” allows an analysis of the effects upon radiated fields due to changes in single nets, groups of nets, entire printed circuit boards, and most importantly, complete systems combining boards, cabling and enclosures. This tool shows results relative to changes. It does not yield absolute field values for comparison to actual laboratory measurements.

10. Remcom Inc.

State College, PA

Phone: (814) 353-2986

Fax: (814) 353-2986

Software: XFDTD

Description: 3D full-wave Finite Difference Time Domain (FDTD) software allows users to decrease the cost and time required to bring new products to market by eliminating unnecessary generations of expensive physical prototypes. The simulation software provides for early evaluation in the design process without the need for actual fabrication. XFDTD is a full wave electromagnetic solver based on the Finite Difference Time Domain method. It is fully three- dimensional. CAD objects may be imported into XFDTD and combined and edited within XFDTD using the internal graphical editor. Plane wave excitation or voltage and current sources can be used to excite the structure. XFDTD has an extensive list of important features, including lumped loads, impedance, S parameters, near/far zone fields, antenna radiation and efficiency, SAR peak and averages, special materials, graphical display capabilities, and many others. Optional modules include multi-processor module, human body meshes, and 3D Solids and Layered CAD Importers.
