Hi,
I didn't want to discourage. It is great to have design acceleration tools to keep managers happy then lose your job at the end. We all have licenses and companies will pay for such tools readily. We all use cores but there is tool race and a variety(C => HDL, C => fpga,Matlab => fpga,Labview => fpga,
... and vendor cores). Of these vendor cores are popular in the industry but as go up you lose the actual understanding of underlying concepts and get engaged with tool related problems and this slows it down.
May be the new generation will make better use of it.
