There are leading edge tools available for PADS Suites at an attractive price level see the links for more comprehensive information.
PADS HyperLynx DC Drop is an easy-to use tool to analyze voltage levels in power planes. The quality of planes has become more critical as the operating voltages are getting lower, so there are less margins for logical levels.
PADS HyperLynx DDR supports DDR1, DDR2 ja DDR3 type memories. The controller, chips, topology and simulations are defined using wizards, making it lot easier. Simulations are run in batch, resulting easy-to-read results with Pass/Fail information for each signal.
PADS HyperLynx DRC is a scriptable tool to analyze and extensive set of rules, mechnical and SI and EMI.
PADS FlowTherm XT is a based on FlowTherm’s technology. It is based on 3D flow analysis and provices accurate results in complex cases by simulating the airflow in the chassis.
