Hello!
Thank you for your response I looked into the .fit.rpt file, here is the snippet of it:
+------------------------------------------------------------------------------------------+
; Fitter Resource Usage Summary ;
+-------------------------------------------------------------+--------------------+-------+
; Resource ; Usage ; % ;
+-------------------------------------------------------------+--------------------+-------+
; Logic utilization (ALMs needed / total ALMs on device) ; 0 / 933,120 ; 0 % ;
; ALMs needed [=A-B+C] ; 0 ; ;
; [A] ALMs used in final placement [=a+b+c+d] ; 0 / 933,120 ; 0 % ;
; [a] ALMs used for LUT logic and register circuitry ; 0 ; ;
; [b] ALMs used for LUT logic ; 0 ; ;
; [c] ALMs used for register circuitry ; 0 ; ;
; [d] ALMs used for memory (up to half of total ALMs) ; 0 ; ;
; [B] Estimate of ALMs recoverable by dense packing ; 0 / 933,120 ; 0 % ;
; [C] Estimate of ALMs unavailable [=a+b+c+d] ; 0 / 933,120 ; 0 % ;
; [a] Due to location constrained logic ; 0 ; ;
; [b] Due to LAB-wide signal conflicts ; 0 ; ;

So, if I understand correctly, no logic resources (ALMs) were used to implement this negation?:
assign Q = ~ A;
Does that mean that I can use the negation of every bit in my project and it won't generate additional logic resources?
