Electronic design automation systems and methods for functional reactive parameterized cells (FR-PCells) are described. In one embodiment, a PCell includes a reactive parameter that is based on context information regarding other cells or elements of an overall circuit design. Processing of the FR-PCell may then depend on processing of other PCells or other elements of a circuit design. Similarly, an FR-PCell may provide context information to other FR-PCells. In some embodiments, processing of an FR-PCell to generate an instance of the FR-PCell is managed by a reaction engine that monitors updates to context information or other PCells to automatically adjust instances of the FR-PCells.

An integrated semiconductor device having a thyristor includes outer npn-transistors, outer pnp-transistors, and an inner npn-transistor. The outer pnp-transistors and the inner npn-transistor are interconnected so as to form a thyristor to allow the inner transistor to be biased into conduction. Furthermore, a current flow takes place via the outer npn-transistors and the inner npn-transistor. The integrated semiconductor device having a thyristor minimizes interference produced in neighboring components.
