High Level Synthesis tool

Hi,

I am currently learning about FPGAs and I am trying to compare the biggest manufacturer's tools.

I have found a very promising High Level Synthesis tool for Xilinx FPGAs, called Vivado HLS.

Does Altera have similar tool for their own products?

I am looking for a tool to design FPGA (not soft core processor) implementations using high level languages (C/C++).

What product Altera suggests for such purposes?

Thanks.
