As discussed earlier, while ASICs take 6 months to several years to develop, FPGA development takes weeks to months. Therefore, FPGAs allow for faster market release. The NRE (Non-recurring Engineering) costs of ASICs are very high. They range from millions to tens of millions of dollars. Therefore, FPGA-based hardware solutions are cost-effective in comparison. However, ASICs may need to be considered when mass production is required (approximately 100,000 units or more). ...

If an FPGA can be compared to a breadboard, then an ASIC is like a PCB. PCB(https://en.wikipedia.org/wiki/Printed_circuit_board#/media/File:SEG_DVD_430_-_Printed_circuit_board-4276.jpg) The photo above is a PCB. To be precise, it has components mounted on top of it. It is commonly used in various home appliances such as smartphones and TVs. To create a PCB, you need to draw a Schematic (circuit diagram). Then, create a PCB layout design. Finally, have it manufactured by a PCB manufacturer. If there is an error after manufacturing is complete, you must fix it. Do you need to change a PCB line (trace) or component? What steps should you take? To have a normal product, you need to modify the Schematic and PCB layout and manufacture it again. Of course, you can cut the line in the middle and connect it with an external wire. However, this will greatly reduce the stability of the product sold. ...

FPGA: Field Programmable Gate Array To take the Bread Board as an example… Bread Board (https://en.wikipedia.org/wiki/Breadboard#/media/File:Ultrasound-PreAmp-Breadboard.jpg) The photo above shows a breadboard. Breadboards are used to temporarily test prototypes. They usually have strips on both sides to extend power lines. The interior is divided into abcde and fghij sections where components or wires can be connected. This allows you to implement desired functions and test them with frequent changes. You can think of the components plugged into the breadboard as modules designed in HDL. The wires connecting them can be viewed as wire declarations in HDL. The placement of the components is similar to the Placement process in FPGA Implementation. Connecting the wires is akin to the Routing process. ...
