![]() It was a useful term in the past for describing the complexity of an IC. VLSI refers to Very Large Scale Integration.For a comparison, think of creating a castle using Lego blocks versus creating a castle using concrete The difference in case of ASIC is that the resultant circuit is permanently drawn into silicon whereas in FPGAs the circuit is made by connecting a number of configurable blocks.These design styles include the design of high-volume products such as memory chips, high-performance microprocessors and FPGA In digital CMOS VLSI, full-custom design is hardly used due to the high labor cost. The design productivity is usually very low typically a few tens of transistors per day, per designer.Field programmable gate arrays (FPGAs) provide the advantages of custom CMOS VLSI while avoiding the initial cost, time delay and inherent risks of traditional mask gate arrays Programmable interconnect resources provide routing paths to connect the input and output of CLB and IOB to the appropriate network.Home FPGAs vs custom VLSI What is the difference between FPGA and other programmable ![]()
