- Vivado is used with -fsm_extraction one_hot. Starting with Vivado 2016.3 this triggers fsm recognition and re-coding of two gray counter modules. This not only defeats the purpose of the gray coded counter, it also caused some constraints to fail. Added attributes to prevent fsm extraction - the logic of `connect_hw_server` and `get_hw_servers` changed after Vivado 2015.1. The `make <design>.vconfig` command worked up to Vivado 2016.2 due to some recovery mechanism, and finally broke with 2016.3. Fixed the call to `get_hw_servers`.
