Following are some examples of typical
HTML reports generated for different purposes, showing the various types
of information that can be included in these reports.
waiver report (Figure 4) enables the recipient to review proposed
waiver shapes with error markers. Multiple snapshots at different zoom
levels can be included to ensure a clear understanding of the affected
geometries. Identical shapes can be categorized under the same rule
check to save review time, and each snapshot can contain a pop-up tip to
explain the error details.

Electrical reliability verification
viewing electrical rule checking results (Figure 5), a histogram can be
calculated on a desired property (e.g., ERROR%) to help analyze the
error severity, while a colormap can display the current density map. If
no snapshot is specified, the reporting process automatically generates
an error table and sorts by the selected property, to further aid data

colormaps assist the recipient in locating the error and understanding
its impact on the design.
Summing it up,
replacing manual error reporting with an automated reporting capability
such as Calibre RVE’s HTML Reporting provides a number of benefits to
both the report generator and the report recipient:
report generation enables layout engineers to facilitate team
collaboration by providing a report that can be quickly screened to
identify the most severe design issues. These issues can be assigned to
the most experienced engineers for analysis, while remaining issues can
be debugged simultaneously by other team members. Not only do you reduce
the overall time required for debugging, but you can ensure the most
efficient and effective use of your engineering resources.
snapshots and standardized (yet customizable) text explanations replace
manually compiled documentation, enforcing data consistency and
accuracy while freeing up engineering resources for more valuable work
and reducing time to market.
- By using a web server for report
access, not only are frequent and often time-consuming file transfers
between the foundry and design house no longer needed, but any number of
recipients can access the report at any time. In addition, tighter
security can be enforced through the web server architecture to ensure
that reports are only available to those with the appropriate access.
physical verification complexity grows, the need for automated
assistance is driving the delivery of capabilities such as Calibre RVE’s
HTML Reporting. By automating time-consuming and error-prone reporting
tasks, and implementing new delivery mechanisms, the HTML reporting
capability not only improves the accuracy and efficiency of the
debugging process, but it also returns valuable time to the process flow
that can be used to improve designs and deliver them to market more
