The yield enhancement techniques in Synopsys' Galaxy Design Platform, particularly the Astro product's ability to insert redundant vias and efficiently enforce antenna rules
, helped us significantly optimize our design and achieve our 90-nm yield targets.
This demonstrates that Magma software supports TSMC's manufacturing rules for 90-nanometer technology, such as complex antenna rules
, via farm rules and metal rules for nine layers of metal routing.
HiPer Verify[TM] is now able to perform antenna rules
checks including NET AREA RATIO, NET AREA, NET AREA RATIO PRINT, and incremental connectivity extraction (DRC INCREMENTAL CONNECT & DISCONNECT).
Special antenna rules
and handling of minimum area rules for vias are among the specific features required for these small geometries.
Other features include: dynamic update of crosstalk nets during detail route; automatic post-route buffering and sizing; optimized pin targeting; track assignment; and antenna rules
that accommodate hierarchy.
0 helps designers achieve optimum routing through consistency checks for TSMC process specific design rules, including multiple wire spacing rules, double via rules, antenna rules
1 version of the detailed router in Dolphin provides full support for the latest process rules including minimum area rules, antenna rules
and end-of-line rules.
These include complex wide-wire spacing rules, minimum area rules, double-cut via requirements for signal wires and pins, advanced hierarchical process antenna rules
, new requirements for copper process technologies, metal density checking and fill, and metal slotting/splitting.
