    I also confirm this annoying bug. It's shame quartus is lacking such basic support of VHDL 2008 features. I took me a few days to find out why my design was not working. Today I also realized that conditional assignment in process VHDL 2008 feature is not working. Quartus simply synthesize logic away.

       rx_pkt_len_proc : process(clk_avmm) is
   begin
      if rising_edge(clk_avmm) then
               ready <= '1';
               ready <= '0' when ready = '1';
      end if;
end process;
