5.(Optional with 10 bonus points) Design a 64-bit adder with a module name of add64, which takes in 64-bits input X, Y to generate the 64-bit sum S, and carry-out bit C. To generalize the design for n-bit adder, we may use parameter as follows parameter n=64; // 64 bit adder input [n-1:0] X, Y;// use of parameter n (a) Briefly describe your algorithm / pseudo codes (b) Write your Verilog design

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
