How does high level synthesis work?
High level synthesis (HLS) [1], also known as behavioral synthesis and algorithmic synthesis, is a design process in which a high level, functional description of a design is automatically compiled into a RTL implementation that meets certain user specified design constraints.
What is high level synthesis in VLSI?
High Level Synthesis (HLS) can be defined as the automated designing process that transforms the behavioral or functional description of the design into a digital hardware implementation.
What is HLS for FPGA?
The Intel® HLS Compiler is a high-level synthesis (HLS) tool that takes in untimed C++ as input and generates production-quality register transfer level (RTL) code that is optimized for Intel® FPGAs. This tool accelerates verification time over RTL by raising the abstraction level for FPGA hardware design.
What is Xilinx HLS?
The Vivado High-Level Synthesis compiler enables C, C++ and SystemC programs to be directly targeted into Xilinx devices without the need to manually create RTL. Vivado HLS is widely reviewed to increase developer productivity, and is confirmed to support C++ classes, templates, functions and operator overloading.
Why is high level synthesis HLS developed?
The goal of HLS is to let hardware designers efficiently build and verify hardware, by giving them better control over optimization of their design architecture, and through the nature of allowing the designer to describe the design at a higher level of abstraction while the tool does the RTL implementation.
What is HLS RTL?
High-level synthesis (HLS) and register transfer level (RTL) are two popular methods to design FPGAs. On the other hand, RTL development enables the developer to make lower level design decisions which can increase the performance and efficiency of the system.
What is Xilinx software used for?
Xilinx serves the aerospace and defense industry with commercial, industrial, military, and space grade products. Emulation & Prototyping with FPGAs enables fast and accurate SoC system modeling and verification of embedded software.
What is synthesis and implementation?
Synthesis is the process of transforming an RTL-specified design into a gate-level representation. Implementation means the various steps necessary to place and route the netlist onto the FPGA device resources.
Why is high-level synthesis?
Why is high-level synthesis HLS developed?
What is RTL synthesis?
In computer engineering, logic synthesis is a process by which an abstract specification of desired circuit behavior, typically at register transfer level (RTL), is turned into a design implementation in terms of logic gates, typically by a computer program called a synthesis tool.
What is high level synthesis (HLS)?
High level synthesis (HLS), also known as behavioral synthesis and algorithmic synthesis, is a design process in which a high level, functional description of a design is automatically compiled into a RTL implementation that meets certain user specified design constraints.
What is the use of HLS?
HLS allows software engineers to design and implement applications, such as SDRs, on FPGAs using a familiar programming language to code, namely C, C++, SystemC, and MATLAB, without the need to posses a prior rich knowledge about the target hardware architecture (refer to Section 4.1). Óscar Lucía,
What is high-level synthesis design flow?
High-level synthesis design flow for power electronic control system design. Together with the algorithm to implement, the HLST takes as an input a set of constraints defined by the designer in order to perform the RTL synthesis.
What is the best approach to implement a new HLS solution?
HLS works well with a modular design approach. It can produce IPs and with the right interface naturally fit into the IP reuse and creation strategy.” Sean Dart, senior group director for R&D in Cadence, focused on the quality and flexibility of implementation.
