Innovation Customization Optimization

ThunderUltimate System Integration Solution

OVERVIEW

ThunderTM is a unique tape-out level layout editor with built-in XOR, density and Boolean engine. It seamlessly combines an efficient database, powerful analysis engine with intuitive GUI. It handles huge layout data in excess of 500+GB of different formats, including GDS, OASIS, LEF/DEF, and OpenAccess, and performs complex geometrical operations accurately in a fast and robust manner. It provides C++/TCL/PYTHON/PERL interface for software developers to develop their own applications.

MAJOR FEATURES

ThunderTM has been tailored to help developing customized solutions in terms of performance and ease of use. AnaGlobe keeps expanding the state-of-the-art features into ThunderTM. ThunderTM is architected to process very large size of IC/SOC with smallest DB at any technology node in the least amount of time.

FASTEST LVL COMPARISON

ThunderTM provides fastest LVL comparison, linear to data size, with GUI visualization to quickly identify differences of two designs. Customer benchmarks show that ThunderTM LVL requires minimum runtime memory usage and completes the comparison even for industry’s biggest chips. (Fig-1)

TAPE-OUT LEVEL LAYOUT EDITING

ThunderTM enables user to browse/edit several hundred gigabytes GDS/OASIS. The intuitive GUI is as friendly as popular layout editors. It provides advanced layout editing features, such as Smart Flatten and snapping to DRC marker, ideal for DRC bug fix.

BOOLEAN OPERATION

ThunderTM provides intuitive multiple-Boolean expression to generate shapes on original design directly.

DENSITY MAP GENERATION & CHECKING

ThunderTM provides fastest interactive density map generation and violation checking with GUI visualization. It provides density variation checking, which is critical for advanced technology node. (Fig-2)

IP MERGE AUTOMATION

ThunderTM provides system integration for IP from GDS/LEF/DEF files with great flexibility such as standard cell replacement, don’t-change list, etc. It performs layout comparison during renaming, which eliminate unnecessary renaming. It supports hierarchical IP merge with incremental change. It generates a summary of missing cells, renamed cells, identical cells, and cross-reference.

FAILURE ANALYSIS

ThunderTM provides a series of functionality to assist the tedious defect inspection job, such as KLA result viewing, image overlay and extraction, pattern grouping and matching, voltage contrast analysis, FinFET 3D view, cross-section, etc. (Fig-3)

HUGE CAPACITY DRC/LVS/DEFECT EXPLORER

ThunderTM provides seamless integration with 3rd party layout verification and wafer inspection tools. It helps the user to navigate and debug DRC/LVS errors and defects efficiently (opens 5G+ DRC results in 7 minutes).  It also supports Calibre short isolation result with 3D display and cross probing. (Fig-5)

DUMMY FILL PATCHING

ThunderTM can fill dummy patterns to low density area interactively with target percentage. It creates vertical/horizontal patterns with offset. It can also take Calibre DRC marker as the target area. (Fig-6)

HIGHLIGHT MISSING VIAS ON POWER/GROUND NETS

To eliminate IR-Drop effect, ThunderTM can perform a quick analysis on power/ground nets to highlight areas with missing vias and fix them by inserting vias.
