Omega PLUS is now augmented by the Ground Plane Modeller module. With this module, Omega PLUS simulates two-sided boards and multilayer boards with partial power and ground planes.

Figure 1 shows a board with an open region. This opening in the ground plane allows electromagnetic emissions, from the layer below, to pass through. In Figure 2 the board has split planes. Also, tracks crossing power and ground plane discontinuities experience sudden changes in track impedances.

According to Mike Ventham, Vice President Engineering, “Omega PLUS builds on the technological leadership of Quantic acquired in 17 years of simulation software development. This latest advancement – accomplished in partnership with SimLab Software GmbH, of Munich – is unique to the Electronic Design Automation industry. With it, accurate simulation of boards with discontinuous grounds and no grounds can now be achieved. This is a major advance to the electronics manufacturing industry - especially for consumer products development – in order to accomplish reliable high-speed designs under these circumstances.”
