COMPLIANCE: Predicts emitted field patterns for systems of PCBs including cabling and enclosures
EMC Simulation
Building on its expertise in the Boundary Element Method (BEM) technology, Quantic has developed Compliance, the first comprehensive EMC simulator available. Compliance allows engineers to see 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.
Cables and enclosures
The user is able to build enclosures with cabling and orient them in any desired way directly in the interface. Complex enclosures can be designed using a solids modelling package and imported into Compliance. The boards can then be positioned within the enclosure and the equipment under test (EUT) can be positioned and oriented in any desired way on the virtual measurement turntable.
Displaying the Results
Compliance displays the vertical, horizontal and radial electric and magnetic fields, either together or separately. Compliance displays maximum field vs. frequency, as well as the fields at the observation points in a three-dimensional graph resembling the measurement positions used in a testing facility. The direct field contributions from the individual nets can be displayed as well as the coupled field contributions from the induced currents on the enclosure, cabling, ground planes and substrates. Compliance can also display the current spectrum of each net on a board, as well as the current waveforms of each component pin. The induced currents on the enclosure can be displayed as a colour surface plot.
Anechoic Test Facility The Compliance user interface functionality mimics that of an anechoic chamber testing facility or open area test site. Engineers are able to set the orientation of the EUT, mast and support hieght, radial distance, and mast and rotational steps. Compliance also provides internationally recogized test standards such as FCC Part 15 and EIC CISPR and allows specific test standards to be defined by the user.
