What is VisualHDL?

VisualHDL is an integrated development environment (IDE) rapid design for FPGAs. It is based on THDL++ - a C++-like language with fully paralell VHDL semantics. It allows developing fully parallel FPGA designs having the flexibility, modularity and maintainability of C++ code. The IDE supports code completion, code navigation, design visualization and tons of other useful features. The IDE is fully integrated with Xilinx ISE toolchain. Moreover, a command-line THDL++-to-VHDL compiler can be used in conjunction with any other tool, that supports VHDL.

Is it a C++-to-FPGA compiler?

No, VisualHDL is a new-generation tool. Instead of converting the inherently sequential C++ code into fully parallel VHDL synthesizable for FPGAs, VisualHDL brings the productivity of C++ and C++ IDEs to the FPGA world. The THDL++ language provides a C++-like syntax, supports object-oriented features, templates, inheritance and reflection, while being fully parallel by design. We use VisualHDL internally for designing highly flexible FPGA IP cores for our customers.
