Honored ContributorHow to blink clock (CLK) in register?
Register code
module reg8 (CLK, D, Q);
input CLK;
input D;
output Q;
reg Q;
always @(posedge CLK)
Q = D;
endmodule
output LED;
...
assign LED = CLK;
Honored Contributoryou can if you want. But if CLK is 50MHz, you wont see it blink.
Honored Contributormy CLK is less than 50MHz
Honored ContributorHi,
What is the frequency of clk? Try simple switch and led program.

Qn-1|Qn
-------
0 | 1
1 | 0
always @(posedge CLK)
Hi,
1.Have you implemented a logic on fpga for 555 IC? Use simple PLL and counter, The MSB bit of counter can be given to the led. 2.Probe and check if clock is generated? or try simple program for example Control led by switch.

--- Quote Start --- i use external timer 555 (CMOS) --- Quote End --- Can you just give information how FPGA, 555 & LED's are interfaced? --- Quote Start --- How? --- Quote End --- Refer below link for steps. https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/tt/tt_my_first_fpga.pdf http://www.armadeus.org/wiki/index.php?title=simple_blinking_led Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
