Honored Contributorerror using Altera FIFO megafunction
Hello.
i've configured FIFO megafunc in such way as on img1 then i've tried to test its operating in such way
module incomingCMD ();
tri0 FULL, EMPTY, CLR, Q;
tri0 CMD;
tri0 USEDW;
reg CLK, RDREQ, WRREQ;
reg command;
assign CMD = command;
assign CLR = 0'b0;
initial
begin
CLK <= 0'b1;
RDREQ <= 0'b0;
WRREQ <= 0'b1;
end
always
begin
# 10 CLK <= ~ CLK;
end
initial
begin
# 20 command <= 0'b1;
# 30 command <= 0'b0;
# 50 command <= 0'b1;
# 70 command <= 0'b0;
# 90 command <= 0'b1;
# 20 command <= 0'b0;
# 70 command <= 0'b1;
# 10 command <= 0'b0;
# 50 command <= 0'b1;
# 80 command <= 0'b0;
# 20 command <= 0'b1;
# 40 WRREQ <= 0'b0;
# 20 RDREQ <= 0'b1;
end

.clock(CLK),
.data(CMD),
.rdreq(RDREQ),
.sclr(CLR),
.wrreq(WRREQ),
.empty(EMPTY),
.full(FULL),
