ABOUT CROSSFIRE

Standard cell library, IO and Hard IP validation tool

Crossfire reports mismatches or modelling errors for Libraries and IP that can seriously delay an IC design project.

State of the art SoC design needs to rely on a correct-by-construction principle for the design creation flow. The increasing number of components from different suppliers and the amount of process corners that need to be covered lead to an explosion in both data-volume and data-variety. Crossfire can help in achieving a working design within a predictable flow by ensuring that every design step is validated and every imported IP-component is qualified.
Crossfire helps CAD teams and IC designers achieving a high quality of design data in a short time.

Crossfire assures that the information represented across the various views is consistent and does not contain anomalies.

Crossfire Diagnose

Diagnose is the Crossfire GUI designed for users that just want to analyze the Crossfire results. The setup and test definition sections of Crossfire are completely shielded from the user.

The user can view, report, filter, waive and analyse the generated Crossfire messages. Reports can be generated as HTML on a “per rule” or a “per format” basis. It’s possible to get more info on the generated messages and the analyse button can display the formats with errors and/or can generate graphical plots from the data. Waiving rules can easily be generated for undesired (error) messages and can be exported to a (pre-defined) directory location (Click & Waive).  Previously stored “waiving rules” can be inspected, edited, and disabled if desired.
