Synopsys SpyGlass Lint is an integrated static verification solution for early design analysis with the most in-depth analysis at the RTL design phase. 22 Aug 2016 User?Training?Tracks Getting?Started?with?SpyGlass Li t?&?SoC Lint S C Lint Li t . Lint in VLSI using Spyglass Linting in VLSI is the process of checking the program code (static code analysis) against a set of design rules and generating a report with all details of violations. Pre-Requisites Ability to analyze design for Clock-Reset Create models for PLL and IO cells if required Create test constraints for memory and other blocks Creating Models for PLLs If PLL has an external bypass in testmode, no action is required Otherwise, replace the PLL model with a reduced model which will propagate test clock to outputs correctly in testmode (can be a simple gated buffer model) - Use only 4-state (01XZ) logic Use module_bypass SGDC constraint to define input -> output path of black box March, 10 Creating Models for IOs If IO is synthesizable, no action is required If you are OK with analyzing from the inbound side of the IOs, no action is required Otherwise, replace each IO model with a reduced model which will propagate the pad signal to inbound signals correctly in testmode - Use only 4-state (01XZ) logic Creating Models for Memories, Other IP For each model: If IP has an external bypass in testmode, no action is required If IP is known to make provision for upstream and downstream scan, add scanwrap constraint: scanwrap name
