表性的微處理器PICDEM2，其中載有PIC18F452液晶，TC74溫度傳感器，24LC256的I2CEEPROM存儲(chǔ)器，RS232串口終端和各種按鈕，LED燈等。2.圖表輸入我們對(duì)ProteusVSM的使用證明Capture軟件提供的環(huán)境設(shè)計(jì)工程和開展是功能強(qiáng)大的。ISIS的建立是一個(gè)長期的過程，產(chǎn)品的易用性與強(qiáng)大的編輯工具都經(jīng)歷了很長時(shí)間的改進(jìn)，它能夠支持兩個(gè)示意圖捕捉模擬和PCB設(shè)計(jì)，設(shè)計(jì)進(jìn)入到VSM測(cè)試可以使用netlisted的PCB布局或者我們自己設(shè)計(jì)PCB產(chǎn)品或與第三方PCB布局工具聯(lián)調(diào)。ISIS還提供了一個(gè)高程度的控制，對(duì)圖紙外觀，線寬，填寫樣式，字體等進(jìn)行控制，這些功能的充分利用為我們提供了必要的電路圖形動(dòng)畫。3.電路仿真最核心的ProteusVSM是ProSPICE。這是一個(gè)既定的產(chǎn)品，是使用SPICE3模擬仿真器內(nèi)核與快速事件驅(qū)動(dòng)結(jié)合起來的數(shù)字仿真，提供無縫混合模式模擬，使用的是SPICE的內(nèi)核，你可以利用任何制造商提供的SPICE模型進(jìn)行封裝。Proteus的VSM包括一些虛擬儀器如示波器，邏輯分析儀，函數(shù)發(fā)生器，圖形發(fā)生器，計(jì)數(shù)器定時(shí)器和虛擬終端以及簡單的電壓表和電流表。此外，我們提供專門的主/從監(jiān)視器模式協(xié)議分析器的SPI和I2C，它們是串行線的監(jiān)測(cè)或與生活中的數(shù)據(jù)模擬。如果你想詳細(xì)測(cè)量的圖表，或執(zhí)行其他分析類型，如頻率，失真，噪音或掃描分析模擬電路，可以購置高級(jí)模擬期權(quán)。此選項(xiàng)還包括一致性分析，一個(gè)獨(dú)特和強(qiáng)大的工具還有軟件質(zhì)量保證。4.協(xié)同仿真單片機(jī)軟件最令人興奮的和最重要的特征是Proteus的VSM是能夠在模擬軟件之間的互動(dòng)關(guān)系上運(yùn)行的微控制器使得任何模擬或數(shù)字電子產(chǎn)品都能連接到它。該微控制器模型示意圖將您的產(chǎn)品設(shè)計(jì)的其他內(nèi)容連接在一起。它模擬執(zhí)行你的目標(biāo)代碼〔機(jī)器代碼〕，就像一個(gè)真正的芯片。如果程序代碼寫入端口，邏輯電平電路會(huì)相應(yīng)地改變，然后這個(gè)狀況的改變就會(huì)通過處理器的針腳輸出，這將使您能夠看到您的程序代碼，就像在真實(shí)硬件中一樣。在VSM中的CPU型號(hào)完全模擬I/O端口，中斷，定時(shí)器，通用同步和所有其他外圍設(shè)備上的每一個(gè)處理器。為什么一個(gè)這么簡單的軟件模擬器可以模擬這么多外設(shè)呢？因?yàn)樗羞@些相互作用的外設(shè)與外部電路完全仿真到波形水平和整個(gè)系統(tǒng)。VSM甚至可以模擬設(shè)計(jì)包含多個(gè)處理器，因?yàn)樗梢院唵蔚膶蓚€(gè)或兩個(gè)以上的處理器的原理圖和線在一起。5.源代碼級(jí)調(diào)試VSM的獨(dú)特性在于，它的功能運(yùn)行接近實(shí)時(shí)模擬完成微控制器系統(tǒng)，但是它真正的功能來自于能夠利用單步模式執(zhí)行這些功能，這個(gè)工程就像是最適合你的軟件調(diào)試器，通過單步調(diào)試代碼，你可以觀察整個(gè)設(shè)計(jì)：包括所有的電子產(chǎn)品外部微控制器。VSM在許多方面到達(dá)這一目標(biāo)，你使用的是依賴于處理器和工具的功能。如需第三方編譯器支持的ProteusVSM的詳細(xì)資料，請(qǐng)參閱第三方編譯頁。調(diào)試窗口的PIC24虛擬Explorer16設(shè)計(jì)。所示的源代碼顯示斷點(diǎn)和兩個(gè)高級(jí)別和低級(jí)別的指示，監(jiān)視窗口擴(kuò)展名為.SFR，擁有可變的窗口擴(kuò)展復(fù)合類型和用戶配置IDLOC內(nèi)存轉(zhuǎn)儲(chǔ)。6.診斷消息VSM配備了全面的診斷或追蹤信息。這使您能夠指定哪些部件或外設(shè)的處理器在任何特定時(shí)間都能收到所有活動(dòng)的詳細(xì)的文字報(bào)告和系統(tǒng)的相互作用。作為一個(gè)調(diào)試這是非常好的功能，讓您查找和解決軟件和硬件問題的速度遠(yuǎn)遠(yuǎn)超過你對(duì)物理樣機(jī)工作時(shí)的速度。診斷安裝與仿真參謀跟蹤信息利用數(shù)字液晶顯示字母工作模式。7.周邊模型庫除了微處理器型號(hào)和數(shù)以千計(jì)的'標(biāo)準(zhǔn)'的被動(dòng)模式，它支持所有類型，對(duì)TTL的CMOS，存儲(chǔ)器等的ProteusVSM是配備了全面的嵌入式外設(shè)庫模式，由字母和圖形液晶顯示器，通過直流，BLCD和伺服電機(jī)的以太網(wǎng)控制器芯片。8.為什么選擇Proteus的VSM？中選擇適宜的軟件解決方案時(shí)，往往容易忽略的是產(chǎn)品可提供哪些功能，特別是當(dāng)一些軟件公司提供成套乍看之下可能看起來是相同的功能時(shí)，Proteus的VSM是第一個(gè)微控制器協(xié)同仿真包，并能提供更多更詳細(xì)的模型。嵌入式系統(tǒng)設(shè)計(jì)的微控制器和完整的模型以及它的準(zhǔn)確度是核心，因此是至關(guān)重要的。你應(yīng)始終確保微控制器仿真模型不僅支持外圍您要使用的設(shè)備，而且支持的式要在其中使用外設(shè)和令人滿意的詳細(xì)程度。
