Before starting the discussion on what is ASIC and what is FPGA, we will first learn about the basics that a VLSI enthusiast should know. Moore’s Law: Moore’s law is the observation that the number of transistors in a dense integrated circuit doubles about every two years.
Candidates from relevant branches are considered for the opening – Electronics, Electrical, VLSI, Digital Electronics.“Our vision is to be a leading VLSI design service provider. Quality, Customer success & TTM are our key goals”
Physical design is process of transforming netlist into layout which is manufacture-able [GDS]. Physical design process is often referred as PnR (Place and Route) / APR (Automatic Place & Route). Main steps in physical design are placement of all logical cells, clock tree synthesis & routing.
Why CMOS? Output of all CMOS cells will be very close to rail-rail (may not be in case of Pass Transistor) With constant input to any cell, power dissipation is only due to leakage currents. Power dissipation increase if activity factor is more (Short circuit current + charging & discharging of load)
A System on Chip (SoC) is an integrated circuit that integrates all components of an electronic systems. It may contain digital, analog, mixed-signal, and radio-frequency modules—all on a single substrate. SoCs are very common in the mobile computing market because of their low power-consumption
