曾有多少次您为设计中各个变量与可编程逻辑的搭配而冥思苦想,不知自己的设计是否适应某种专用器件?其变量之多,诸如门电路的数量、逻辑电路的种类、存储器电路的类型、逻辑电路与存储器电路的比率、半导体厂家采用的结构、半导体厂家的器件、设计的入口方法:软件厂家的工具集及工具集修改后版本的序号等,数不胜数。而当您采用另一个厂家的器件或工具集时,情况发生变化,又该如何去处置?这些问题每周在因特网新闻组comp.arch.fpga上都要讨论许多次。
How many times have you pondered over the mix of variables and programmable logic in your design, knowing that your own design fits into a specific device? Many of its variables, such as the number of gates, the type of logic, the type of memory circuit , The ratio of logic circuits to memory circuits, the structures used by semiconductor manufacturers, the devices of semiconductor manufacturers, the method of entry for designs: the number of software vendors’ toolsets and the modified version numbers of their toolsets. And what happens when you use a device or toolset from another vendor and how to deal with it? These issues are discussed many times a week on the internet newsgroup comp.arch.fpga.
