  • Magma, ARM, GLOBALFOUNDRIES

    Introduction
    Monday morning at DAC I attended the breakfast presentation from Magma, ARM and GLOBALFOUNDRIES. The 28nm node is ready for business using Magma tools and ARM libraries.

    During breakfast I met Karim Arabi, Ph.D. from QualComm. He's a senior director of engineering in San Diego and wanted to learn more about the 28nm node and how Magma tools could be used in a flow.

    Notes


    Rod Metcalf – Magma, 28nm Reference Flow Development, using the Talus flow manager for the entire IC design flow. We ran a testcase to ensure silicon validation. Goal is to use the Magma flow on a 28nm Global Foundries process and get 1st silicon success.

    - Use the existing libraries which are characterized at specific corners, or create your own corners.
    - They used an OpenCore design as their reference example.
    - ARM supplied the 28nm libraries, standard cells, memories. Multi Vt libraries were used.
    - Talus from Magma: The RTL-to-GDS II tool flow. Offers high capacity, silicon proven at 28nm, high speed designs.
    - Low power technologies used, CPF and UPF.
    - Talus Flow Manager: a way to capture a complete tool flow. Analysis results are in HTML, easy to read or email complete with links for more details. Pie charts, timing violations.
    - Talus Flow Manager – the reference flow provides correct setups for all tools needed, much less work for users to

    GLOBALFOUNDRIES – Our largest competitor reports their test chips as tape-outs, we don’t count those as tape-outs.

    Summary: Flow of Magma tools and ARM libraries on the GLOBALFOUNDRIES 28nm process are ready to go now, proven, validated.


    Jim Ballingall, Ph.D. VP Marketing – GLOBALFOUNDRIES uses high K metal Gate (HKMG). Photo of a quad-core CPU with a GPU from AMD producing 500Gflops performance (beats Sandy Bridge from Intel).

    - Ramp of HKMG process is going well. Gate first HKMG approach (Intel uses Gate last HKMG). Intel is using FUD, don’t believe it.
    - Market requirements for foundry customers.
    o 28nm SLP (Super low power) – low mask count, no stress engineering for lowest costs
    o 28nm HPP (High performance process) – uses stressors, >3GHz performance,
    - Gate first can be 10 to 20% smaller std cells with Gate First compared to Gate Last approach
    - CPU speed versus cost: SLP is lower clock speed and lower cost, while HPP is higher speed and higher cost

    Global Solutions – an ecosystem with EDA tool vendors, mask making, assembly. A successful program.
    - Design Kits for 28nm SLP are ready now, HPP coming soon.
    - Investment of $5.4B in 2011 for GLOBALFOUNDRIES.

    Common Platform Partners – IBM, Samsung, ST (Fab synch agreement)

    Dresden Fab 1 – plan for 1 million wafers per year at 45nm and below nodes

    Fab 8 in NY – shell is complete, equipment moving in, on schedule. 60K wafers/month.

    Multi Program Wafers (MPW) – run every quarter, fully subscribed, allow lower costs.

    20nm – In development now, partnered with IBM. Results due in 2012/2013. First shuttles started in 2011 Q4.

    Q&A

    Q: What about fin FET?
    A: Looks like a 14nm technology to us.

    Q: Is 20nm Gate Last?
    A: Yes, that’s true. We choose that for fewer design rules. Gate First was good down to 28nm. At 20nm litho dominates and we choose Gate Last.

    Q: What about DFT?
    A: We partner with companies like SynTest for DFT tools, they can be integrated into our Talus Flow Manager like any Magma tool.
