当FPGA作为ASIC(专用集成电路)的廉价替代品首次面市时广受欢迎。FPGA不仅没有掩膜成本,而且易于修改设计。似乎FPGA只需要不断提高容量,就能够取代大部分产量有限的ASIC了。然而,经验表明,小容量FPGA在替代量产定制逻辑时更受青睐。造成这一局面的原因之一是硅片成本。在给定 When the FPGA as ASIC (Application Specific Integrated Circuit) cheap replacement for the first time the market is very popular. Not only does FPGA not mask costs, but also easy to modify the design. It seems that FPGAs can replace most of the ASICs with limited production capacity by constantly increasing their capacity. However, experience shows that small-capacity FPGAs are more favored when it comes to replacing mass-customization logic. One of the reasons for this situation is the cost of silicon. Given
