Introduction of 2.5D and 3D multi-die based products are helping extend the boundaries of Moore’s Law, overcoming limitations in speed and capacity for high-end computational tasks. In spite of its critical function within the 3DIC paradigm, the interposer die’s role and related challenges are often neither fully comprehended… Read More
Cadence made waves a while back with its innovative Clarity 3D Solver, a FEM solver for near field EM analysis. Now they are shaking things up with their new far field Clarity 3D Transient Solver. System level EMI and EMC analysis has often exceeded the limits of simulation tools, leading to expensive and time-consuming prototype… Read More
Designers spend a lot of time looking at their layouts in 2D. This is done naturally because viewing in 2D is faster and simpler than in 3D. It helps that humans are good at extrapolating from 2D to 3D. Analysis software, such as extraction software also spend a lot of time looking at layouts in 2D. While this is fine for approximate results,… Read More
Mentor Graphics made a big announcement regarding SOC extraction at their User2User conference in San Jose during April. Before I get to the meat of the announcement, I’d like to reflect back on the early days of Calibre-DRC at Mentor. I was in Sales at Mentor around 1999, and Calibre-DRC was the new kid on the block. We had to go convince… Read More
Introduction
3D field solvers produce the most accurate netlists of RC values of your IC layout that can then be used in SPICE circuit simulators however most of these solvers produce a flat netlist which tends to simulate rather slowly. Thankfully several years ago the first hierarchical SPICE tools were offered by Nassda (HSIM… Read More
