Accurate, fast P2P resistance extraction for unconventional geometries
Automated 2D fracturing techniques provide fast, accurate P2P resistance extraction in unconventional IC design structures
IC design layouts that include large or wide metal structures require multiple P2P resistance measurements between different probing points for accurate extraction of resistance. However, field solvers, which are the traditional tool of choice, can be difficult to use and require long runtimes. 1D fracturing simplifies the fracturing to improve performance, making it insufficient by itself for these unconventional geometries. 2D fracturing can be used to fracture the metal structure in both directions to create a resistance mesh of r-bodies, enabling accurate extraction of P2P resistance values. The Calibre® PERC™ reliability platform enables accurate, automated selection of suitable fracturing techniques based on the design metal structures and the specified probe points, ensuring accurate P2P resistance measurements and simulation while minimizing runtimes.
