1、 論文題目：USB3.0-GPIB 控制器設(shè)計(jì) 專(zhuān) 業(yè)：微電子學(xué)與固體電子學(xué) 碩 士 生：楊翠翠 （簽名） ： 指導(dǎo)教師：朱向東 （簽名）： 摘要 GPIB， 是一種廣泛應(yīng)用于電子測(cè)量?jī)x器的通用接口總線(xiàn)， 它具有并行總線(xiàn)傳輸速度快、驅(qū)動(dòng)能力強(qiáng)、通信距離遠(yuǎn)、抗干擾性能好及通用性等特點(diǎn)，利用它

2、可以將電子測(cè)量?jī)x器和計(jì)算機(jī)組建成一套積木式、模塊化的自動(dòng)測(cè)試系統(tǒng)。要組建基于 GPIB 總線(xiàn)的自動(dòng)測(cè)試系統(tǒng)，核心是 GPIB 控制機(jī)。實(shí)現(xiàn) GPIB 控制機(jī)最簡(jiǎn)單的方法是在計(jì)算機(jī)上連接一個(gè) GPIB 控制器， 而 GPIB 控制器上必須要有能與計(jì)算機(jī)直接相連的接口。 傳統(tǒng)的 GPIB控制器一般都是基于 RS232、ISA 或 PCI 總線(xiàn)協(xié)議，在使用過(guò)程中存在著安裝麻煩、不適合移動(dòng)式測(cè)量、價(jià)格昂貴、受計(jì)算機(jī)插槽數(shù)量等多種問(wèn)題。本課題針對(duì)

3、基于傳統(tǒng)接口總線(xiàn)的 GPIB 控制器在使用中出現(xiàn)的多種問(wèn)題， 將新的 USB3.0 技術(shù)融入到 GPIB 控制板卡的設(shè)計(jì)中，使得新的 USB3.0-GPIB 控制器速度更快、通用性更好、功耗更低。 本課題的主要內(nèi)容由三部分組成：第一部分為 USB3.0-GPIB 控制器硬件電路設(shè)計(jì)與實(shí)現(xiàn)。 其中包括 USB3.0 接口和 GPIB 接口電路的設(shè)計(jì)及實(shí)現(xiàn)接口控制的 FPGA 平臺(tái)。USB3.0 控制芯片選擇 CYPRESS 公司的 CYU

4、SB3014 芯片，因 GPIB 接口芯片受到專(zhuān)業(yè)用途的限制，價(jià)格昂貴、購(gòu)買(mǎi)不便等的影響，本課題采用 Verilog HDL 語(yǔ)言來(lái)實(shí)現(xiàn)基于FPGA 的 GPIB 控制芯片 IP 核， FPGA 則選用 ALTERA 公司的 EP3C16F484 工業(yè)級(jí)片子。第二部分主要實(shí)現(xiàn)基于 USB3.0 接口的 FPGA 與電腦之間的數(shù)據(jù)通信。此部分包括USB3.0 的固件設(shè)計(jì)、FPGA 控制 USB3.0 芯片讀寫(xiě)操作設(shè)計(jì)以及 FPGA 控制

5、2 片 DDR2進(jìn)行乒乓倒數(shù)據(jù)傳輸?shù)脑O(shè)計(jì)。第三部分主要實(shí)現(xiàn) GPIB 接口控制芯片的 IP 核的設(shè)計(jì)。GPIB IP 核的設(shè)計(jì)包括各個(gè)接口功能模塊的設(shè)計(jì)、讀寫(xiě)控制模塊的設(shè)計(jì)、配置寄存器模塊的設(shè)計(jì)及終端模塊的設(shè)計(jì)等。 實(shí)現(xiàn)以上內(nèi)容后，將三部分內(nèi)容整合到 USB3.0-GPIB 控制器板卡上進(jìn)行調(diào)試，調(diào)試工作主要包括 USB3.0 的枚舉測(cè)試、 USB3.0 數(shù)據(jù)流的測(cè)試分析及 GPIB IP 核各功能模塊的編譯與仿真。經(jīng)測(cè)試設(shè)計(jì)的 USB

6、3.0-GPIB 控制器成功實(shí)現(xiàn)了基于 FPGA 的 USB3.0與電腦四個(gè)線(xiàn)程的穩(wěn)定、正確的數(shù)據(jù)通信，GPIB IP 核各功能模塊功能驗(yàn)證正確。 關(guān) 鍵 字：USB3.0；FPGA；GPIB；固件；IP 核 研究類(lèi)型：應(yīng)用研究 Subject : The Design of The USB3.0-GPIB Controller Specialty : Microelectronics and solid state electr
