AMSFAB’s Process Design Kit s  (PDK) can be integrated into the mainstream EDA simulation software  to realize the complete and diversified RFIC /MMIC  design. The PDK s   have both of active devices and passive multi-functional modules , sub-circuit models, symbols and layouts with adjustable parameters  of elements , electromagnetic simulation models , b ehavior models , and convenient interfaces, which make circuit design more intui tive , more accurate and faster.
