Indeed. I was working at a startup doing some FPGA work about 10 years ago. We ran into several bugs in the Xilinx software. Initially we could submit bugs, but about 6 months in Xilinx suddenly changed their policy and decreed that only tier 1 customers (definitely not us) could submit bugs - everyone else had to look for help on the forums. We spent a lot of our time just working around the bugs in their tools. At that point I determined that, though FPGA development was kind of fun and interesting, I would not go into a field where I was going to be dependent on such buggy software and went back to the software side (where pretty much all the development tools are open source and if you run into trouble you're going to be able to get help).
