But the most of posting here were about 3D EM software. AWR and Eagleware both have not real 3D simulation modules. When I asked about comparing I mean network simulators and layout tool. Speed, accuracy, user interface.
Speed, accuracy, even user interface are trade-off.
The most quick way to compare with them without brain is to
(1) compare with their product cost.
(2) or you can check simulation tool appearance propotion from IEEE paper.
Besides, different tool got their own characteristic and can not be compared
easily. As I known, there are some engineers using genesys for PLL simulation
and some engineers using AWR for microwave circuit simulation.
