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)

fa3f5e0d65
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!)
