 tilelink has the disadvantage that it was designed by people who
think in high-level languages.  i don't believe they ever actually
looked really closely at the auto-generated verilog and thought, "if
this standard became popular and people tried to implement it from
scratch in verilog or VHDL, how much effort would they need to

 consequently it's hell to implement in anything other than an
OO-based HDL.  IIT Madras, who are using Bluespec, are having
well-above-average difficulties implementing it.

 fun as it would be to get into a pissing contest with ARM and have
all the claims invalidated by crowd-sourced prior art searches like
cloudfare did against that patent troll last year, we have better
things to do with our time.
