Suppose there's two SDT_LOGIC_VECTOR signals A_READ and A_OUT, both 8 bits wide. A_READ is updated by some process at random intervals. A_OUT is connected to 8 LED's.
I want to blink a LED for each bit in A_READ that has changed since the last check. Checking interval should be fixed at around 10 milliseconds. LEDs should blink once for about 100 milliseconds.
How can this be done using a CPLD?
