VHD2VL - free and opensource translator for synthesizable VHDL into Verilog 1995/2001. It does not support the full VHDL grammar - most of the testbench related features have been left out. Syntax and semantics are not carefully checked. vhd2vl assumes that the input is error-free.
Vhd2vl is written using lex (actually Flex), yacc (actually Bison), and C.

The most important VHDL constructs missing from this version are
◦ packages
◦ structures
◦ functions
◦ strings
◦ attributes

CLaaS - Custom Logic as a Service.
This solution, it significantly reduces the complexity of developing a hardware-accelerated application, bringing the platform within the reach of everyone, including startups, open-source enthusiasts and makers. With the framework, you can stream data directly between your custom FPGA kernel and application using standard websockets.

OpenSTA - the engine for gate level static timing verifier. As a stand-alone executable it can be used to verify the timing of a design using standard file formats. OpenSTA uses a TCL command interpreter to read the design, specify timing constraints and print timing reports.

Xilinx Vitis slides from today's presentation:

Bring Your Applications to Life with Vitis

#Xilinx #Vitis #HLS #FaaS #AI #Alveo #SDAccel #SDSoC

#VitisAI has been released today at the #xdf2019 and is available for download now.

In a nutshell: it is the tool that takes your trained #tensorflow or #caffe model and optimises it for your #Xilinx hardware.
Or very simply spoken: the turbocharge for #versal-devices and their AI engines.

HDL Checker - a language server that wraps VHDL/Verilg/SystemVerilog tools that aims to reduce the boilerplate code needed to set things up. It supports Language Server Protocol or a custom HTTP interface; can infer library VHDL files likely belong to, besides working out mixed language dependencies, compilation order, interpreting some compilers messages and providing some static checks.

RgGen - a code generation tool for ASIC/IP/FPGA/RTL engineers. It will automatically generate source code related to configuration and status registers (CSR), e.g. SytemVerilog RTL, UVM RAL model, Wiki documents, from human readable register map specifications.

Features:
◦ Generate source files related to CSR from register map specifications
◦ SystemVerilog RTL
◦ UVM RAL model
◦ Register map documents written in Markdown
◦ Register map specifications can be written in human readable format:
◦ Ruby with APIs to describe register map information
◦ YAML
◦ JSON
◦ Spreadsheet (XLSX, XLS, OSD, CSV)

Xilt - Command Line Tools for Xilinx Toolchain. Xilt assumes Xilinx ISE WebPack 14.7 is installed and only works on 64-bit Linux systems (this is a deliberate design decision since the ISE isn't officially supported on current versions of Windows).

Xilt can be used to:
◦ Build VHDL, Verilog and mixed mode FPGA projects.
◦ Runs xst, ngdbuild, map, par and bitgen all from one command invocation
◦ Filters output to show errors and warnings while suppressing all other messages
◦ Launch common Xilinx GUI tools (ISE, CoreGen and License Manager) without having to explicitly setup ISE environment paths
◦ Build places all intermediate files into a separate folder to keep your source folders clean

Usage example:

xilt build --device:xc6slx9-2-tqg144 myproj.vhd myproj.ucf

Datasheet Scrubber - a utility that scrubs through large sets of PDF datasheets/documents in order to extract key circuit information. The information gathered is used to build a database of commercial off-the-shelf (COTS) IP that can be used to build larger SoC.

Datasheet Scrubber also define IP-XACT++, an extended version of IP-XACT, to encapsulate all the information needed for system generator, and port known IPs into the database. Doing this is really useful in finding the optimum SoC design based on user specifications.

Yet Another VHDL tool performs parsing, semantic analysis, and elaboration. The goal is to at some point in the future integrate this with the yosys HDL synthesis tool.

Apparently, that's good starting point to develop your own VHDL parser.
