The current open source FPGA tools are in no way a replacement for commercial offerings like
in the year 2000, Linux was in no way a replacement for Solaris from Sun Microsystems.
Open Source gives any interested developer the possibility to look under the hood and tailor the current offering to his own needs. So the open source FPGA toolchain is able to fill some needs currently not addressed by commercial tools.
As Python as a tool was a boost to the accessibility and ease of programming, we need progress in the FPGA field towards easier and more powerful tools, so that not only Electronics engineers, but software developers and even researchers them self can build FPGA solutions.
