Regarding Verilog HDL .... Xilinx recommends control signals in modules be coded so they are active high. Why?
Homework Answers
That's really a catch and very interesting to stumble
upon.
We know that active low signals requires an inversion (which
subsequently adds a LUT in the path) before they can directly drive
the control port of a register (refer RTL). And, by using extra
LUTs and routing resources with the of active low signals, we would
create timing problems and consume more power. Also, if you're
using the active low clocks, you would require extra LUT for each
clock, this would create the unnecessary requirement of more and
more LUTs in total and make the design more power sinking. Better
avoid it, please. :)
If you're new to LUTs read a quick overview below:
FPGA implements combinational logic with the help of LUT short for
Lookup table, which basically is the truth table of the outputs for
given inputs. LUTs can be used to implement any given logic
operators like AND, OR, NOT, NOR, NOR, XOR, XNOR etc.

i just want the code
Write a module in Verilog HDL that describes a parallel load shift register. The following are the requirements for the shift register • The shift register shifts right by one position at a time The shift register size (in bits) is set by a parameter called WIDTH The shift register has a parallel data bus input for loading a value in parallel. The parallel bus is called datalp. The size of the dataly, bus uses...
