Celltroy Technologies Cell Compiler “Ardon” Overview
2
Problems in Standard Cell Libraries and UDSM For UDSM technologies OPC and PSM create very complex context based design rules. Cost of library development and design changes doubled in last 2 years. Industry waste 10 bln $ on yield and hand-work changes (Design Yield Cost Model, ЕЕ Times 2005) 2
3
Problems in 65 nm and lower Complex context based design rules made hand work very expensive. Library variation: need several versions of the same cell based on usage context. Design rule change imply cell redesign. Need specialized automation tool for library designers. 3

5 Project Goals Automation of activities related to standard cell library Optimization Leakage power Yield improvement Generation Gridless and adaptive routing Template based fast generation Migration

6 Underlying technology Multicriterion, multiparameter cell optimization (solution of dynamic programming problem) Integrated simulation, LVS, DRC, RC Extraction, characterization, Statistically optimized transistor placement 1.5D Compaction with DRC Tool can be embedded in to existing flows Tool can connect 3 rd party tools via plugin model

Competitors – Synopsys Cadabra The main competitor with solid client base Strengths Automatic creation flow. Semi-automatic migration flow Weaknesses Standalone tool provided as service. Need Circuit-Explorer, HSPICE, Hercules and Star-RCXT which makes him ~$1M tool. Clients Agere, Cypress, Delco, IBM, MIPS, National, Qualcomm, Vitesse, TI, Intel, Micron, HP, Rockwell, Cisco, ST, Analog Devices, Matushita, Toshiba, Sony, Sharp, Fujitsu, Renesas, TSMC, HuaJie, UMC, Hynix Opportunities Providing compatibility with the existing Cadabra projects format can push to try Ardon. 7

Competitor – Compactors Compaction tools provide only the ability to migrate libraries Sagantec (Dream and Hurricane) Market leader in layout compaction Virtuoso Layout Migrate Former Q Design Automation (Q-Trek) Strengths Ability to migrate large designs up block/chip level Weaknesses Lower quality of layout due to of fast, generalized algorithms designed to shrink larger designs. Limited to linear scaling, does not handle architecture changes. If compaction does not meet design objectives, the fall-back is manual layout. Opportunities Customers who have libraries that require architectural changes. Customers that have to create/recreate significant number of new cells. Customers who require high quality of results 8

Competitor – 3 rd Party Libraries 3 rd party libraries obviate the need for a potential customer to develop a library in-house. ARM (Artisan) SAGE, SAGE-X, SAGE-HS, Metro. Can be purchased under per chip-royalties. Virage ASAP, ASAP metal programmable libraries TSMC, Virtual Silicon Strengths Can eliminate upfront costs under a per-chip licensing model Off-the-shelf availability Weaknesses “Free library” is more expensive in long run Libraries are general purpose, not optimized for functions and drive strengths. Library vendors can add custom cells, but it is expensive, lose control of IP. Reduces ability to differentiate. Opportunities Customers can quickly create libraries that optimized for specific conditions (power, performance, speed, area, yield). Thus synthesis tools can produce better results if there is a richer library available. 9

Milestones Leakage power optimization for UDSM technologies (DONE) Yield optimization (28 Dec 2007) Multicriterion optimization and visualization (28 Dec 2007) Automatic generation (template based) (1 May 2008) Handling whole library (DAC’2008) Create 400 cell library with different drive-strengths (at least 200 need to have hand-made quality) Support characterization Do automatic datasheet generation Support all-views Need to be all-in-one. One tool covering all flow. 11
