PCIe

因為PCIe高頻寬以及低延遲性的特性,PCIe是現在及未來的高速傳輸介面主流技術,尤其廣泛應用在各種伺服器,於各式硬體裝置之間的高速訊號傳輸: CPU to GPU, CPU to network interface card (NIC), CPU to accelerator, CPU to SSD等。
艾飛思科技更為PCIe測試專家,提供PCIe 1.0至日前最新一代PCIe 6.0一致性訊號驗證測試服務,並為PCI-SIG規範工作小組的夥伴之一,也是PCI-SIG每季研討會指定Gold Suite夥伴。 艾飛思科技致力於提供業界最完整的PCIe測試解決方案,除了RX、TX、PLL及PCIe 5.0/6.0測試治具之外, 我們還有目前業界少見的PCIe 5.0協議測試分析服務。
此外,PCIe 6.0 Compliance test(合規驗證)比對之前的PCIe 5.0驗證規範多了兩項測試: RLM(Ratio of level mismatch)以及SNDR(Signal-to-noise and distortion ratio),RLM是衡量訊號不同電平之間不匹配程度的指標。不同電平之間的距離應該是一致的,以確保訊號準確性。由於硬體設計或訊號傳輸過程中的不理想情況,可能會出現不匹配現象,RLM幫助檢測電平之間不匹配的程度,以確保訊號的可靠性。SNDR表示訊號與噪聲和失真之間的比值,包括所有的噪聲和失真成分。SNDR數值越高,表示訊號質量越好,噪聲和失真相對成分越少。
