ASIC and FPGA design advantages and process comparison

ASICs and FPGAs have different value propositions, and you must carefully evaluate them before choosing one. The comparison information of the two technologies is very rich. Here are the advantages and disadvantages of ASICs and FPGAs.

Comparison of design advantages between FPGA and ASIC
FPGA design advantages ASIC design advantages
Faster time to market - no wiring, masking and other manufacturing steps are required. Full Custom Performance - Achieve design because the device meets design specifications.
No NRE (temporary expense) - Cost associated with ASIC design Reduced unit cost - for high volume design
Reduced design cycles - because the software can handle many routing, layout, and implementation issues. Miniaturization - The device meets the design specifications.
A more predictable project cycle - due to the elimination of possible re-spin, wafer capacity, etc. Higher internal clock speed
Field reprogrammability - a new bitstream that can be uploaded remotely.

In the past, FPGAs were used for designs with low speed/complexity/capacity, and today's FPGAs can easily break through the performance barrier of 500 MHz. FPGAs offer unparalleled increases in logic density and a host of other features (such as embedded processors, DSP blocks, clocking technology, and high-speed serial) at a lower price, and are now almost the design of choice for any design.

Comparison of design flow between FPGA and ASIC
The FPGA design flow eliminates complex and time-consuming layout, layout and routing, timing analysis, and mask/project re-spin stages because the design logic has been integrated into validated, featured FPGA devices.

However, when needed, Xilinx also offers advanced floorplanning, hierarchical design, and timing tools that enable users to maximize the performance of designs that require FPGAs and ASICs to compare to the most demanding designs.
