Hello Dear Readers, Today in this post, I will provide some deep insight into the VLSI packaging evolution and innovations. Semiconductor packaging has evolved from a simple protective housing into a critical performance enabler. In the modern VLSI landscape, packaging is no longer an afterthought; it is a fundamental determinant of PPA (Power, Performance, and Area) metrics, often dictating the thermal limits and signal integrity of the final SoC. 1. Traditional Packaging Technologies: These methods are the workhorses of the industry, widely used for low-to-medium complexity devices where cost-efficiency is paramount. Wire Bonding (QFN, QFP, DIP): Wire bonding is the most mature interconnection technology. It uses thin gold, copper, or aluminum wires to connect the die's bond pads to the package's internal leadframe. Implementation: The die is attached face-up to a leadframe or substrate. A wire bonder uses thermocompression or ultrasonic energy to attach wires betwee...
Hello Dear Readers, Today in this post I will be providing you a complete Verilog code of 4 Bit BCD Adder using the Full Adder instant model. So before the start, the code keep in mind the algorithms for the BCD adder is if the additional sum is greater than 9 will become up then we add 6 on it to make a valid BCD number so here in my code I have used this algorithm so keep in mind. Verilog Code: module bcd_4bit(input [3:0] x,y,input cy_in,output [3:0] sum,output carry,output [4:0] bcd_sum); add4 a1 (carry,sum,x,y,cy_in); assign bcd_sum=carry==1?{carry,(sum+4'b0110)}:sum; endmodule module add4(cy4,sum,x,y,cy_in ); input [3:0] x,y; input cy_in; output [3:0] sum; output cy4; wire [2:0] carry_out; add b0(carry_out[0],sum[0],x[0],y[0],cy_in); add b1(carry_out[1],sum[1],x[1],y[1],carry_out[0]); add b2(carry_out[2],sum[2],x[2],y[2],carry_out[1]); add b3(cy4,sum[3],x[3],y[3],carry_out[2]); endmodule module add(carry_out,sum,a,b,cy_in ); input a,b,cy_in; outpu...
