WP362-利用設(shè)計(jì)保存功能實(shí)現(xiàn)可重復(fù)的結(jié)果

  　　FPGA 設(shè)計(jì)不再像過(guò)去一樣只是作為“膠連邏輯 (Gluelogic)”了，由于其復(fù)雜度逐年增加，通常還會(huì)集成極富挑戰(zhàn)性的 IP 核，如 PCI EXPRESS® 核等。新型設(shè)計(jì)中的復(fù)雜模塊即便不作任何改變也會(huì)在滿足 QoR(qualityof-result) 要求方面遇到一些困難。保留這些模塊的時(shí)序非常耗時(shí)，既讓人感到頭疼，往往還徒勞無(wú)功。設(shè)計(jì)保存流程可以幫助客戶解決這一難題，既可以讓他們滿足設(shè)計(jì)中關(guān)鍵模塊的時(shí)序要求，又能在今后重用實(shí)現(xiàn)的結(jié)果，從而顯著減少時(shí)序收斂過(guò)程中的運(yùn)行次數(shù)。

PICMG_COM_0_R2_0COMe規(guī)范--原文資料

A Computer-On-Module, or COM, is a Module with all components necessary for a bootable host computer, packaged as a super component. A COM requires a Carrier Board to bring out I/O and to power up. COMs are used to build single board computer solutions and offer OEMs fast time-to-market with reduced development cost. Like integrated circuits, they provide OEMs with significant freedom in meeting form-fit-function requirements. For all these reasons the COM methodology has gained much popularity with OEMs in the embedded industry. COM EXPRESS® is an open industry standard for Computer-On-Modules. It is designed to be future proof and to provide a smooth transition path from legacy parallel interfaces to LVDS (Low Voltage Differential Signaling) interfaces. These include the PCI bus and parallel ATA on the one hand and PCI EXPRESS and Serial ATA on the other hand.
