6 years agoHow am I inferring latch in this code?
I'm getting warning 10631 in Quartus II (inferring latches)
Warning (10631): VHDL Process Statement warning at U6D2CPUSeq.vhd(947): inferring latch(es) for signal or variable "RST_RSMRST_N_200MS_DELAY", which holds its previous value in one or more paths through the process
Warning (10631): VHDL Process Statement warning at U6D2CPUSeq.vhd(947): inferring latch(es) for signal or variable "RST_RSMRST_N_200MS_CNT", which holds its previous value in one or more paths through the process
here is my code:
process(LED_500HZ_CLK, RST_RSMRST_PLD_R_N_T, RST_DEDI_BUSY_PLD_N)
begin
if RST_RSMRST_PLD_R_N_T = '0' or RST_DEDI_BUSY_PLD_N ='0' then
RST_RSMRST_N_200MS_DELAY <= '0';
RST_RSMRST_N_200MS_CNT <= (others =>'0');
elsif rising_edge(LED_500HZ_CLK) then
RST_RSMRST_N_200MS_CNT <= RST_RSMRST_N_200MS_CNT + '1';
if RST_RSMRST_N_200MS_CNT = "1100100" then
RST_RSMRST_N_200MS_DELAY <='1';
end if;
end if;
end process;
