Evaluating Speedcore IP For Your ASIC (WP007)

Phase zero is the beginning of a Speedcore design and how you begin matters. From a technical perspective, you will want to explore the possibilities to maximize the benefit of having your ASIC deployed with a Speedcore instance with a mix of resources well suited to your current and future programmed configurations. Achronix will help you along this road, providing support, training and feedback in employing tools, benchmarking designs and dealing with optimization issues.

EFPGA Acceleration in SoCs — Understanding the Speedcore IP Design Process (WP008)

The Speedcore design and integration methodology has been defined with intimate awareness of the difficulties ASIC engineering teams must contend with. All the necessary files and flows for capturing the functional, timing and power characteristics of a user-defined and programmed Speedcore instance, along with support for successfully reconfiguring an already field-deployed Speedcore IP embedded in an ASIC, are available to an ASIC development team either as products of the ACE design tools or as deliverables provided by Achronix. This methodology has already been proven in silicon and readily accommodates variations and preferences in company-specific ASIC development methodologies.

Embedded FPGA – a New System-Level Programming Paradigm (WP006)

The current public debate on the future of the semiconductor industry has turned to discussions about a growing selection of technologies that focuses instead on new system architectures and better use of available silicon through new concepts in circuit, device, and packaging design. The emergence of embedded FPGA is, in fact, not only essential at this juncture of the microelectronics history, but also inevitable. To understand this, a review of the history of FPGA technology is in order.

Using FPGAs to Accelerate Data Centers (WP005)

With the technology industry at a crossroads — the effective repeal of Moore's Law  — data centers have become the sweet spot of the technology sector, showing healthy revenue growth and attracting new system solutions in both hardware and software. Unlike the ethereal promise of upcoming wonders from AI, robotics and the IoT, data center growth and innovation is happening in the here and now, with an even brighter future ahead the moment other nascent markets emerge from their chrysalis with killer apps of their own.

Coding Guidelines for Speedcore eFPGAs (AN003)

In order to obtain the best quality of results (QoR) when targeting any design to an FPGA, it is sometimes necessary to structure the RTL and constraints to take best advantage of the underlying FPGA architecture and the built-in features of the tool chain.

Routing Reset Signals on Speedcore eFPGAs (AN007)

In FPGA design, reset signals can sometimes have a significant effect on the overall quality of timing or routing results. Generally it is recommended to reduce the number of logic elements that need to be reset by taking advantage of initial values and coding in such a way that reset is only needed on a few end points.

Measuring Accurate Toggle Rates

When calculating dynamic power for a design, one input to any power estimation is the toggle rate of the signals. In most circumstances, the value used will be one of the industry standards of either 12.5% or 25% — values derived from a wide range of designs.

Formal Verification in the ACE Flow (AN013)

This application note covers the formal verification support available in the ACE environment. ACE currently is capable of supporting formal equivalency checking in its design flow, enabling the user to verify the synthesized netlist against the output at the different stages in the ACE flow.

Speedster7t IP Component Library User Guide (UG086)

The Achronix Speedster7t macro cell library provides the user with building blocks that may be instantiated into the user’s design. These macros provide access to low-level fabric primitives, complex I/O block, and higher level design components. Each library element entry describes the operation of the macro as well as any parameters that must be initialized. Verilog and VHDL templates are also provided to aide in the implementation of the user’s design.

Simulation User Guide (UG072)

The Achronix tool suite includes synthesis and place-and-route software that maps RTL designs (VHDL or Verilog) into Achronix devices. In addition to synthesis and place-and-route functions, the Achronix software tools flow also supports simulation at several flow steps (RTL, Synthesized Netlist, and Post Place-And-Routed Netlist). This guide covers the simulation flow for Achronix devices.
