  1. VDK and HAPS Synopsys Hybrid platform Decreasing your T2M by enabling early software design Uri Shkolnik Zoro Solutions Ltd. June 2014 SNUG Israel

  2. Agenda About Zoro Experience using Virtualizer VDK for ROM development DW_USB3 driver virtualization and emulation Experience deploying Hybrid prototyping VDK↔HAPS

  3. About Zoro Pre-Silicon Software development • Software development using simulation (using tools by Synopsys, and additional EDA companies). • Emulation, virtual and hybrid platforms (HAPS, Virtualizer VDK, others) • Software ASIC verification • Proven experience with ARC, ARM, CEVA, MIPS, Tensilica • ROM development, including RTOS, USB, SDIO, Security (boot, authentication) and additional ROM stacks • Zoro offers turnkey projects, outsourcing and consulting • Synopsys Partner (Virtual Prototyping, ARC, DW IP)

  4. SoC Design Efforts – Past and Present

  5. Traditional SoC Design Approach VLSI SW

  6. T2M SoC Design Approach VLSI SW

  7. Based on a True Story….. • Israeli Fabless Company • SoC Design Start, ARM Cortex w/USB3.0 – Dec 12 • Hardware prototype (FPGA which contains ARM, USB3, memories, UART), to be ready by Mar. 13 (halted, NC) • Emulation, took long time and many efforts, single resource for both VLSI & SW, unsuitable for many software tasks – Summer 13 • Decision to deploy Virtualizer VDK, bare metal – Sep 13 (SW engineers only) • Decision to deploy Virtualizer VDK & HAPS USB3, bare metal and Linux – Dec 13 (done by SW engineers only). Platform runs Linux with good speed

  11. Vertical HW/SW integration: Middleware & Drivers Multi-layer, multi-core, multi-tool SW debugging GDB: Sensor middleware – Cortex A GDB: Sensor driver – Cortex A Lauterbach: Sensor firmware– Cortex M One click connection of a debugger to any thread, on any core, in any SW layer, in non-intrusive stop-mode !

  12. From VDK to Hybrid VDK-HAPS ARM Cortex A5 w/ DW-USB3 SoC OS-less ROM and Embedded Linux Firmware

  13. VDK

  14. Hybrid (VDK + HAPS)

  15. Popular ASIC Prototyping Methods Software Stack Certify Synplify Premier Synopsys Virtual Prototype Identify Virtual (Pre RTL) FPGA-Based (RTL) SystemC/TLM ASICRTL SynopsysVirtualizer SynopsysHAPS Systems Project Timeline

  16. Integrated Hybrid Prototyping Solution Best of Both Worlds Synopsys Hybrid Prototype Solution Generic Interrupt Controller Cortex-A15 MPCore Cortex-A7 MPCore HAPS Systems FPGA-based ASIC prototype Validate HW/SW operation at near real-time speed Virtualizer SystemC/TLM–based virtual prototype Start software development before hardware is available Data Exchange L2 cache controller Interconnect Embedded memories UARTs Color LCD Controller DesignWare USB 3.0 GPIOs RTC Timers DesignWare Ethernet Keyboard / Mouse Interface Generic Battery Watchdog Interface AMBA UMRBus

  17. The Hybrid prototyping:Solution Strengths • Virtualization enables rapid setup, simple development and debugging • FPGA enables high confidentiality with RTL/IP. • The Hybrid setup eases software design comparing to simulation and/or full emulation solution (FPGA, Veloce). • The Hybrid solution provides simple environments (and transactions between) bare metal, RTOS and eLinux. • HAPS provides solution for specific IP/RTL verification and software integration (which cannot be done by purely virtual platform like the VDK/Xplorer, such as PHY) • The Hybrid setup results with longer validation time for both VLSI and SW teams
