May be i din describe correctly.

Actually i want the led to be used a .1s. When 0.1s, 1st LEDon. 0.2s, 1st and 2nd LEDs on. It continues until 1s 10 LEDs on together. and it rotates.

Currently what i do is i use case statement(as explained above) and reg(as 0.1 counter, reach 10 it reset again)

The problem with this coding is if i have a lot of LEDs(other application). The coding will be consuming.

By the way, does verilog have rotate?

Besides, i see a lot of# number in some book means delay. Is this for test bench or RTL modelling or both?

thanks a lot
