HAPS-80 Series FAQ

1. What is new and exciting about the HAPS-80 FPGA-Based Prototyping Solution?

Answer: The new HAPS-80 FPGA-Based Prototyping Solution is the fastest, most affordable way to validate SoC and ASIC designs. The HAPS-80 prototyping solution offers:

  • Performance capabilities to yield 30 to 100 MHz performance for a multi-FPGA design (300 MHz for a single FPGA design)
  • Automated partitioning features to reduce time to first prototype to less than two weeks on average
  • Features for multi-design mode to support enterprise configurations up to 1.6 billion ASIC gates and concurrent design execution
  • Built-in debug capabilities for minimally invasive debug and the ability to capture thousands of RTL signals
  • Support for hybrid use modes and integration with simulation and emulation technologies to save months of design and verification bring-up time
  • Backward compatibility with HAPS-70 to enable reuse of daughter boards and cables

2. What is ProtoCompiler prototyping software?

Answer: ProtoCompiler prototyping software for HAPS is a single tool that allows you to manage prototype board resources, enable debug, partition logic, and synthesize. High capacity, timing-driven partition and system-route engines quickly solve the most difficult partition problems while optimizing for the fastest system clock performance. Logic synthesis for HAPS provides dedicated HDL compilers and optimization tuned to your objective whether it is the shortest bring-up time or highest system performance.

3. Why is the integration of HAPS and ProtoCompiler software important to automate partitioning and accelerate time to first prototype while providing the highest performance?

Answer: Partition automation setup is easier and the results are more reliable because of the HAPS equipment characterization. For example, chip-to-chip latency and connector signal granularity produces higher quality partition floorplans and system route solutions by ProtoCompiler. Time to first prototype is shortened by providing fully automated TDM circuit integration, routing of communication buses and debug instrumentation, and high-capacity debug storage for troubleshooting and protocol validation.

4. Does ProtoCompiler support other prototyping boards?

Answer: No. Synopsys ProtoCompiler is integrated with HAPS systems to deliver the highest system performance unmatched by traditional “budget” circuit boards and FPGA design tools. Detailed hardware knowledge of the HAPS system architecture, high speed connectors, I/O structure, and clocking organization are required to fully optimize a solution that enables ProtoCompiler to provide the highest performance and fastest way to bring-up the prototype environment.

5. What is the new proprietary high-speed time-domain multiplexing (HSTDM) technology and how will this improve performance and the quality of the overall project development?

Answer: The new proprietary high-speed time-domain multiplexing (HSTDM) technology takes advantage of HAPS-80’s new capabilities to deliver maximum multi-FPGA performance with a minimum of devices. ProtoCompiler automatically selects the optimum mix of pin-multiplexing schemes to best match the design under test. The HAPS-80 solution delivers performance of up to 300 MHz for single FPGA designs, global synchronous performance of 100 MHz for multi-FPGAs without chip-to-chip pin-sharing, and up 30 MHz for multi-FPGA scenarios that do require pin-sharing. The increased system performance of the HAPS-80 systems enables OS booting to the command prompt in less than a minute, allowing designers to probe and initialize device hardware such as CPU, timers and UARTs. HAPS-80 also enables at-speed operation of real world I/O.

6. What debug capabilities are included with the HAPS-80 Series FPGA-Based Prototyping Solution?

Answer: HAPS-80 solutions deliver superior debug visibility and automation through always available HAPS Deep Trace Debug Gen4 (DTD4) technology, providing the ability to capture over 1000 debug signal bits per FPGA at speed or seconds of debug data. Debug data acquisition, debug storage memory, and dedicated debug routes are built into the HAPS-80 systems and inserted automatically by ProtoCompiler to ensure minimally invasive debug is always available to the user. These debug features provide an array of capabilities which can be deployed at any stage of the ASIC prototyping project ensuring that the source of a design bug can be located as fast as possible. In combination with the Synopsys Verdi™ debug software, HAPS DTD4 helps designers rapidly visualize complex design behavior in the context of the original RTL source for a simulator-like experience, reducing debug time by up to 50 percent. In addition, HAPS and ProtoCompiler integration with Verification Continuum’s Unified Compile technology enables seamless transition between Synopsys VCS, ZeBu and HAPS to save months of design time.

7. What workstation connectivity solution does the HAPS-80 provide that will enable high-bandwidth communication?

Answer: The Synopsys Universal Multi Resource Bus (UMRBus) is a high-speed communications interface designed into HAPS-80 systems to enable workstation-based access to the FPGA-based prototype. This connection solves the bandwidth and reliability problem with options for USB or PCIe physical connection and a robust API for software driven communication with the physical prototype. Some of the major features of HAPS-80 enabled by the UMRBus include:

  • Up to 400MB/s host connection to DUT
  • C/C++/Tcl API for HAPS
  • USB or PCIe host connection
  • Optional AXI, AHB, APB protocol interface up to 130MB/s

The Synopsys UMRBus host connectivity enables hybrid prototyping, global accessibility and prototype server farm use modes. The UMRBus provides the infrastructure for a seamless link between HAPS systems and Synopsys’ Virtualizer-based virtual prototypes to create an integrated hybrid prototyping environment for early software development and hardware/software integration.

8. What types of testing release criteria are used to ensure the highest quality and reliability of HAPS-80 systems before they are ship to users?

Answer: A combination of extensive testing and strict product release criteria helps ensure that HAPS users enjoy the benefits of high availability, reliability, and functional consistency across units. Hardware characterization conducted by Synopsys includes application tests of interconnect cables, HapsTrak® standard daughter boards, FPGA modules, and power supply modules. Each HAPS system shipped to an end-user site includes a HAPS System Production Test Certificate that provides a summary of the test results for the system assembly. To ensure a high standard of reliability and quality every HAPS system must pass the defined release criteria before the system is released to an end-user.

9. Why should a customer who builds their own FPGA-Based prototype boards or is using another commercial vendor consider the HAPS-80 prototyping solution instead?
