A foundational principle in system design is that a system engineer must be capable of predicting emergent properties of the system, that is, properties possessed by the system but not its parts.
Anasim, a Total Power Integrity consulting team, provides a power integrity aware floor planner pi-fp that employs advanced analysis simplification and distributed IC component representation to provide true-physical analyses. Our novel PI methodology and tool provide front-end chip/pkg/board or system-level physical and electrical design optimization. Our engineering reference book on PI is the first that addresses chip PI in the system context, and continuum modeling (Amazon link). Read more on pi-fp below.

High levels of abstraction and physics-based simulations are key to system-level true-electromagnetic power integrity analysis. pi-fp and its very small set of simulation language constructs allow for simple, distributed representations of power delivery, load, and integrity management structures such as power transmission lines, grids, capacitance, and integrated circuits. Employing the patent pending effective current density algorithm, the pi-fp analysis environment solves for electrical charge flow and corresponding potential variations considering all elements of electrical behavior such as resistance (I*R), capacitance (C*dv/dt), and inductance (L*di/dt) simultaneously. Based on the physics of charge transfer and potential difference, the simulator analyzes and computes true-physical behavior of the modeled system.
