use a 4-bit counter plus a 4-bit mask for tracking delay in every bank
...
this is the optimized delay-tracking mechanism on which the 32-bit shift regs is replaced by a 4-bit counter plus a 4-bit mask. This uses lower resources but still able to track the delays and the exact slot number where the delay is already satisfied (hence no added latency)

use 32-bit shift reg for tracking delay inside every bank
...
There are 4 delays being tracked (delay_before_precharge, delay_before_activate, delay_before_read, and delay_before_write) and 8 banks, that means 32x4x8 = 1024 bits needed for this tracking delay mechanism (totally wasteful!)
