SpyGlass Lint

Early Design Analysis for Logic Designers

Inefficiencies during RTL design usually surface as critical design bugs during the late stages of design implementation. If detected, these bugs will often lead to iterations, and if left undetected, they will lead to silicon re-spins. The SpyGlass® product family is the industry standard for early design analysis with the most in-depth analysis at the RTL design phase. SpyGlass provides an integrated solution for analysis, debug and fixing with a comprehensive set of capabilities for structural and electrical issues all tied to the RTL description of design.


With soaring complexity and size of chips, achieving predictable design closure has become a challenge. A multitude of coding style, structural and electrical design issues can manifest themselves as design bugs and result in design iterations, or worst still—silicon re-spins. Other tools may detect design bugs but often at late stages of design implementation, after a significant investment in time and effort has already been made. As design teams become geographically dispersed, consistency and correctness of design intent becomes a key challenge for chip integration teams. Emphasis on design reuse and IP integration requires that design elements be integrated and meet guidelines for correctness and consistency.
