Calibre users are under constant pressure to improve productivity. Therefore, Calibre engineers are forever looking for areas where performance is at risk. One such area involves the Source SPICE netlists and how they are constructed and stored. This video will describe this issue, how to determine if it is occurring during your Calibre nmLVS run, and how to rectify this problem.
Source SPICE netlists are often built hierarchically and concatenated from multiple sources and at multiple levels. Each level (IP, Block, Macro) may consist of multiple files spread across the network. When this occurs, it can also possess multiple duplicate inclusions to the lower-level libraries. How does this affect your runtime performance? This video provides insight into this issue
