1、德州儀器與DesignSoft公司聯(lián)手為我們的客戶提供 TINA-TI 一個(gè)強(qiáng)大的電路仿真工具，適用于對(duì)模擬電路和開(kāi)關(guān)模式電源（SMPS）電路的仿真。它是幫助設(shè)計(jì)師和工程師們進(jìn)行電路開(kāi)發(fā)與測(cè)試的理想 選擇。TI之所以選擇TINA? 6? 4仿真軟件而不是其它的基于SPICE技術(shù)的仿真器， 是因?yàn)樗瑫r(shí)具有強(qiáng)大的分析能力、簡(jiǎn)單和直觀的圖形界面，并且易于使用，可以讓你在最短時(shí)間內(nèi)啟動(dòng)并運(yùn)行。如果您熟悉其它的SPICE仿真器，那么盡快適應(yīng) TINA-TI將會(huì)是一個(gè)很容易和直接的過(guò)程。盡管 TINA-TI是更加強(qiáng)大的DesignSoft仿真 產(chǎn)品中的一個(gè)有限版本，它仍能輕松處理極為復(fù)雜的電路。德州儀器

2、不確保或支持任何 DesignSoft的產(chǎn)品。TINA-TI是由TI和DesignSoft共同開(kāi)發(fā)的軟件程序。如需獲得DesignSoft的更多信息，敬請(qǐng)?jiān)L問(wèn)DesignSoft的網(wǎng)站：Tina Pro是一款EDA軟件，用于模擬及數(shù)字電路的仿真分析。具有交直流分析、瞬態(tài)分析、 正弦穩(wěn)態(tài)分析、傅立葉分析、可以繪制零、極點(diǎn)圖、相量圖、等等，功能強(qiáng)大，經(jīng)過(guò)個(gè)人使 用效果不錯(cuò)，類似的還有軟件如multisim , ORCAD的Pspice,采用的模型為標(biāo)準(zhǔn)的Pspice。個(gè)人推薦使用此軟件，比multisim更接近于實(shí)際?，F(xiàn)在使用的版本為 V8,目前只在電驢里面好像有資源下載。歡迎下載 The I n
