Spartane-6 LXand LXT FPGAs are available in various speed grades, with -3 having the highest performance. The DC and AC electrical parameters of the Automotive XA Spartan-6 FPGAs and Defense-grade Spartan-6Q FPGAs devices are equivalent to the commercial specifications except where noted. The timing characteristics of the commercial(XC)-2 speed grade industrial device are the same as for a-2 speed grade commercial device. The -2Q and -3Q speed grades are exclusively for the expanded(Q) temperature range. The timing characteristics are equivalent to those shown for the-2 and-3speed grades for the Automotive and Defense-grade devices.Spartan-6 FPGA DC and AC characteristics are specified for commercial (C), industrial (), and expanded (Q) temperature ranges. Only selected speed grades and/or devices might be available in the industrial or expanded temperature ranges for Automotive and Defense-grade devices.

隨著數字信號處理技術和數字電路工作速度的提高，以及對于系統靈敏度等要求的不斷提高，對于高速、高精度的ADC、DAC的指標都提出了很高的要求。比如在移動通信、圖像采集等應用領域中，一方面要求ADC有比較高的采樣率以采集高帶寬的輸入信號，另一方面又要有比較高的位數以分辨細微的變化。因此，保證ADC/DAC在高速采樣情況下的精度是一個很關鍵的問題。ADC/DAC芯片的性能測試是由芯片生產廠家完成的，需要借助昂貴的半導體測試儀器，但是對于板級和系統級的設計人員來說，更重要的是如何驗證芯片在板級或系統級應用上的真正性能指標。ADC的主要參數ADC的主要指標分為靜態指標和動態指標2大類。靜態指標主要有：Differ ential Non-Li nearity（DNL）ntegral Non-Li nearity（INL）Of fset Error ull Scale Gain Error動態指標主要有：

VME has been the de-facto bus standard for Commercial off the Shelf(COTS ) Circuit Card Assemblies since the 1980's. VME boards have proven to be remarkably capable of evolving to support newer technologies with innovations such as VME Subsystem Bus, PCI Mezzanine Cards(PMC's) and VME320.However, advances in technologies, appearing particularly in interconnects, have demonstratedthe need for an advance in system development. This advance needs to accommodate high speed interconnect, particularly serial interconnects, and higher power delivery in concert with better heat removal.
