Release of pi-fp (and source code) to end-users
Anasim releases pi-fp along with its GUI and simulation source code to end-users under a Creative Commons license. The pi-fp project archive may be downloaded from Anasim’s PI-FP page.
Written in C++ and developed in a platform independent development environment (Qt from Nokia®), pi-fp sports an intuitive graphical user interface and 3D interconnect / simulations results visualization. It is the first CAD tool to provide a physical design schematic capture environment as it relates to chip/system power integrity. pi-fp is also the first simulation environment that employs innovative modeling and simulation algorithms (ECD) to include key aspects of power integrity verification in a true-physical manner. In addition to interactive 3D simulation results display, data sets in ASCII form for additional analysis and GNUPLOT scripts for further results visualization are also written out by the software.
pi-fp in its currently released form has been developed entirely by the late Dr. Donald Bennett, Anasim’s co-founder and chief scientist. It was Dr. Bennett’s wish that pi-fp as developed by him be released freely to all for their use, a wish that I am glad to fulfill.

Continuum (Analog) Analysis of Power Integrity
Power Integrity analysis has traditionally been conducted using lumped, discrete elements and circuits, which lead to approximate models and inaccurate results. In continuum-models based analysis, a chip power grid and distribution network is modeled as a continuous surface, employing distributed models for circuits and capacitance. This not only eliminates the exploding computational complexity for power integrity (PI) analysis in nanoscale chips, it facilitates physical, true-electromagnetic simulations for chips, packages, and 3D assemblies. Continuum-models based analysis is “analog” in the sense that a layer to be analyzed is treated as a spatial potential or voltage continuum, similar to analog signals being time-continuous in nature, as opposed to analyzing discrete elements and their interactions.
Read more on this in a SOCcentral featured article. A comprehensive treatment of Continuum Modeling is accessible in Anasim’s PI book for IC’s.

Singapore / May 2008
Anasim co- founder Raj Nair gave a talk on Software, Nano-Hardware and Energy at NanoEquity Asia 2008 in Singapore. Speaking about technology evolution, Raj predicted that software will take its place as a true manifestation of intelligence, and focusing upon energy and cost efficiency, software will emulate natural processes leading to accelerated evolution in machines aiding life.
