人人都在谈论器件综合成本,然而究竟什么叫器件综合成本?简单地说,器件综合成本是指系统中某个特定的器件(在此为PLD器件)在它整个“寿命”过程中,直接归属于该器件的一切费用的总和.许多工程师和采购员评价一个器件的成本时,均以该器件的最初售价为标准.其实,很多情况下,器件的售价在它整个“寿命”过程中,只占该器件所发生总费用的一小部分.实际上,一片PLD芯片最初的购买价只能看作它“寿命周期”中综合成本的起点.随着PLD器件投入装机前预处理阶段,它将继续发生一系列费用.例如来料检验/筛选、库存保管、编程、编程损耗、打印标记和其他处置,亦即PLD器件在发生了一切费用之后才算准备好装电路板.PLD寿命周期综合成本的下一阶段是电路板或整机装配和测试.在这一 Everyone is talking about the overall cost of the device, but what is the total cost of the device? Simply put, the total cost of the device refers to a system in a particular device (PLD device) throughout its “life” process, direct The sum of all the expenses that belong to this device.Many engineers and buyer when evaluating the cost of a device are based on the initial selling price of the device.In fact, in many cases, the selling price of the device is in its entire “life span” process , Only a small part of the total cost of the device.In fact, the initial purchase price of a piece of PLD chips can only be seen as the starting point of its comprehensive cost in the “life cycle.” As PLD devices into the pre-installed pre-processing stage , There will continue to be a series of costs such as incoming inspection / screening, stocktaking, programming, programming loss, print marking, and other dispositions, meaning that the PLD device is ready for board loading after all costs have been incurred. The next phase of cycle cost is assembly or testing of the board or the whole machine
