Give Feedback VHDL wait Constructs

The Intel® Quartus® Prime software supports one VHDL wait until statement per process block. However, the Intel® Quartus® Prime software does not support other VHDL wait constructs, such as wait for and wait on statements, or processes with multiple wait statements.

VHDL wait until construct example

architecture dff_arch of ls_dff is
output: process begin
wait until (CLK'event and CLK='1');
Q <= D;
Qbar <= not D;
end process output;
end dff_arch;
