What is formality Synopsys?
synopsys.com. Overview. Formality® is an equivalence-checking (EC) solution that uses formal, static techniques to determine if two versions of a design are functionally equivalent. Formality delivers capabilities for ECO assistance and advanced debugging to help guide the user in implementing and verifying ECOs.
What are compare points in formality?
Compare points are primarily matched by object names in the designs. If the object names in the designs are different, Formality uses various methods to match up these compare points automatically. You can also match up these names manually when all automatic methods fail.
What is LEC in ASIC?
LEC (Logic Equivalence Check) is the essential step to ensure the functional check between RTL and netlist as can also be depicted from the Fig.
What is a SVF file in Synopsys?
svf – Automated setup file. This file helps Formality process design changes caused by other tools used in the design flow. Formality uses this file to assist the compare point matching and verification process. This information facilitates alignment of compare points in the designs that you are verifying.
What is unreachable points in LEC?
Unreachable unmapped points are key points that do not have an observable point, such as a primary output. Not-mapped unmapped points are key points that are reachable but do not have a corresponding point in the logic fan-in cone of the corresponding design.
What is the need of type equivalence checking?
The major advantage of name equivalence checking is that it is efficient. The check involves ensuring that two types have the same declaration, which can be reduced to a single word comparison in most machines. This advantage goes a long way to explaining the popularity of the scheme within many programming languages.
