can somebody solve this question for me....design using verilog....


with a 2-level NAND block diagram assuming the availability of two-rail logic, implement the function f(X,Y,Z)=XY+X'Z'+YZ'.

if possible, i would appreciate very much if u can provide me with diagrams



and pls tell me what does TWO-RAIL LOGIC means...
 

Re: two rail logic

Two-rail logic means using two levels to describe a HIGH or LOW on two lines. HIGH might be a TRUE '1' on both Lines & LOW might be a FALSE '0' on both lines. Either condition in which one line was HIGH and the other LOW would be an invalid state.

U can have a look of the attachment which can tell u somethin about it in Arithmetic ckts. Hope 2 help.
