Have to chuckle at this one. I worked for a large company that actually got support from Broadcom for a newer part family (StrataGX). The support was dismal. You'd ask an FAE questions, they'd shrug, if you pressed hard enough (and got your executive team in the loop) you'd get an "answer" from the factory which was usually a pile of badly commented Verilog excerpts under NDA. Thanks but no thanks.
Oh and that one time we did get sample code it was a dump of someone's development directory, including project files for another company (you're probably have one of their machines in your office right now). That was fun.
