Status of 65nm foundry access for Aida June 2013 A. Marchioro CERN/PH-ESE

New Commercial Contract Proposal for new foundry contract submitted to CERN FC and approved on March 20 – About same value as previous contract (for both 65nm and new 130nm) – 5 Years – (Current 130nm contract still valid until 2015) Contract details (fine pricing, delivery terms, guarantee, shipping costs, applicable law, etc. etc.) finalized with IMEC Expecting contract signature by mid-Summer Export conditions could be similar if not identical to the ones with previous foundry – i.e. no “free” circulation of some of these chips!!! Status of 65nm 6/132

Legal aspects New foundry has “special” confidentiality culture Foundry is now willing to adapt NDA conditions to HEP clients – New procedure requires new NDAs to be issued to all users by IMEC This was already done with Cadence to allow CERN/Cadence/IMEC to work on new design kit Details for extension to all HEP Institutes being finalized with IMEC Status of 65nm 6/133

Technical Aspects (1) Design Kit – Porting on Cadence OpenAccess with flow similar to old 130nm done by Cadence (Paris + US) – First release received from Cadence Result being qualified and tested at CERN by CERN with demo design – Includes one flavor of digital cells (to be analyzed and eventually modified) from foundry Library, but no RT IO cells Not clear if we can have more than one! Modified library must be returned (and will continue to be owned by the foundry) – CERN has investigated usage of library characterization tool (Altos) but results are still controversial (most cells match data from foundry, others seem to be wrong) – Training courses for new flow to be scheduled asap Status of 65nm 6/134

Technical support and distribution model for new foundry FoundryIMECCERN Institute A University B … Lab Z Status of 65nm 6/135 First training on new flow to be organized at CERN – Later, to be seen

Orders for MPW and Production runs FoundryIMECCERN Institute A University B … Lab Z Status of 65nm 6/136 Dedicated admin contact person assigned in CERN-ME All deliveries to CERN (MPW and productions runs), re- shipped from Geneva

Warning Normal 65nm MPW runs from the new foundry allow for all process options and splits at a fixed price. Designers tend to like these! Some of these options are very expensive in actual productions runs and people are very surprised when the bill is presented. Status of 65nm 6/137 WARNING

Technical Aspects: IPs Regular foundry SRAM generator are not suitable for radiation environment Specifications for Hardened SRAM prepared by CERN Three companies contacted and qualified for providing RadTol SRAM generator – Three offers received Winners to be announced soon – First phase of work to start with CERN-WP1 funds by the summer – Expected first delivery for Q1’14 IPs to be distributed for a fee Status of 65nm 6/138

Technical Aspects: IPs Slow 12-bit, 65nm monitoring ADC: – 4 companies contacted, one selected – Work started with company that provided the 130nm slow ADC cell – Architecture is simple Wilkinson (identical to old DCU in CMS) with improved offset cancelation scheme – Project is funded and delivery expected Sep ‘13 – Submit proto by Q4 ‘13 IP available to everybody in community for a small fee Status of 65nm 6/139

Technical Aspects: IPs CMOS IO Pads – Thick-oxide free minimal library with CMOS 1.2V levels and robust ESD structures compatible with design kit using core only devices – Technical details specified in a document by CERN – Specialized subcontractor identified To be executed in 2 nd ½ of 2013 – Project paid for by CERN – Available to users in HEP community for small fee Status of 65nm 6/1310

Technical Aspects: IPs PLL for generic applications Specs: – Clock multiplier (40MHz -> 1.6GHz) – Low Power (< 5 mW) – Try SEU robustness through TMR – Offers in hands from three design houses – Typical PLL-IP cost: 35K-60K – Access cost for multi-use to be negotiated and paid for by end-user Status of 65nm 6/1311

Technical Aspects: IPs Bandgap reference cell – This cell eventually necessary for all analog designs – Based on experience gained with multiple BG 130nm submission Design to start at CERN in July with EU-Aida funds Submission in November ‘13 – Small funds necessary for proto-chip To be included in IP library for a small fee Status of 65nm 6/1312

Other IP blocks necessary High Speed SLVS cells Optimized STD cells library for pixels? – Characterization and library inclusion I/O Pads optimized for usage with TSVs I/O Pads optimized for bump-bonding Specific CAE tools – working on an early power estimation tool for digital … RT to extreme TID and high flux hadrons validation – Test structures are available – Should this tech not be sufficient for extreme levels, it may require some hard re-thinking of some current projects… Status of 65nm 6/1313

Design style Old foundry accepted many violations (justified through special waivers )to the sacred rule-book New foundry will accept NONE! Status of 65nm 6/1314

130 nm second source Prices from new foundry is lower than current prices No sign that old foundry will discontinue supplying CERN Design kit to be re-spinned by Cadence Design Services after work on 65 nm will be completed – Funds are available – Distribution will be free Introduction and distribution for users in Q4 ‘13. – Possibly new training courses to be organized Status of 65nm 6/1315

Conclusions CERN is committed to continue foundry support to Aida community for new CMOS generation and also for alternative of the current one – 65nm full support model to converge in second part of ’13 IMEC to become official HEP interface to foundry Status of 65nm 6/1316
