Fractal Technologies Wiki

Fractal Technologies is a privately held company with offices in San Jose, California and Eindhoven, the Netherlands. The company was founded by a small group of highly recognized EDA professionals. Fractal Technologies is dedicated to provide high quality solutions and support to enable their Customers to validate the quality of internal and external IP’s and Libraries. Thanks to our validation solutions, Fractal Technologies maximize value for its Customers either at the Sign Off stage, for incoming inspection or on a daily basis within the Design Flow process. Fractal Technologies goal is to become the de facto IP & Library Validation Solutions Provider of reference for the Semiconductors Industry, while staying independent to keep its intrinsic value by delivering comprehensive, easy to use and flexible products.

Crossfire checks consistency and validates all data formats used in designs and subsequently improves the Quality of Standard Cell Libraries, IO libraries and general-purpose IP blocks (Digital, Mixed Signal, Analog and Memories). It reports mismatches or modeling errors for Libraries and IP that can seriously delay an IC design project.

Library and IP integrity checking has become a mandatory step for a “state of the art” deep submicron design due to the following challenges:

  • The sheer number of different views
  • The complexity of the views (ECSM, CCST/N/P)
  • The loss of valuable design time
  • Time to market
Crossfire helps CAD teams and IC designers achieve high quality design data in a short time. Crossfire assures that the information represented across the various views is consistent and does not contain anomalies.

Graphical and batch setup creation, run environment, and batch run support powerful hierarchical configuration language supporting macro functions.

  • Automatic setup generation
  • API’s
  • Viewing and Debugging
  • Waiving mechanism
  • Reporting
  • Transport (QA deck)
Takes a directory with IP collaterals as main input and detects valid formats (design views). Configures applicable checks based on the available formats.

Fractal API for creating database independent checks, available in: Perl, Tcl and Python. Existing customer validation scripts and formats can be integrated. Database API to data-mine information from report database and create custom reports.

Visualization of supported design views (abstract/concrete layout, symbol/schematic, text files, and more). Built-in debugging to view differences in formats (text vs. text). Layout vs. layout differences highlighted. Plots of trends and waveforms. Bottleneck analysis reveals root-cause of an entire category of errors allowing users to quickly make sense of large amount of error messages.

Waive messages that represent false errors or corner cases that won’t impact design quality. Waivers can be saved to file subsequent QA runs.

Detailed summary report of all checks available in HTML or CSV with customizable template.

Transport serves as an input format (YAML-based, aka CFS) to Crossfire, describing what checks the tool needs to execute for specific IP, as specified by the IP integrator.
