If the internal signal driven by the other signal which comes under the clock then first signal will also became the synchronous

Synchronous reset in VHDL. if (clk'event and clk='1') then if reset = '1' then --- elsif ----- end if; end if; Asynchronous reset in VHDL if reset='1' then ------- elsif clk'event and clk='1' then --------- end if; Hope it helps Thanks
