作者：myshitshit 再貼一個測試設(shè)計的職位描述 Job Function: Definition, architecture, modeling, verification, bring-up, debug and support of structural test for achievement of high defect coverage of microprocessor designs from product definition through production. Responsibilities: • Define, model and verify DFT features. • Utilize industry-standard ATPG tools to generate patterns and verify them. • Simulate/verify DFT patterns using Verilog VCS. • Bring-up and debug DFT patterns on the ATE. • Develop, implement and support DFT methodologies. • Proficient with at-speed scan architectures, memory BIST and/or logic BIST. • Proficient with coding/scripting using Perl. • Mentor less senior DFT engineers and lead their efforts in achieving project objectives. • Collaborate with engineering professionals across the company in order to advance the state of the art of DFT and test practices at AMD. Preferred Experience: • Master of EE or above. 4+ years DFT experience. • Experience in microprocessor design or experience in handling complex SOC designs. • Knowledgeable about industrial standards in DFT such as LBIST/JTAG/MBIST. • Knowledgeable about ATE testers and ATPG standard practices. • Expert knowledge of Verilog, RTL, Verilog simulators and waveform debugging tools. • Good debugging capability with both RTL and gate-level simulations. • Good communication skills and the ability to work with geographically distributed design sites. 可以看出要求很多。一些剛進(jìn)入電路行業(yè)的人會認(rèn)為測試相關(guān)的事情技術(shù)含量很低啊，當(dāng)然測試間的操作員是要做很多重復(fù)性勞動。但是測試設(shè)計完全是另一回事。大些的企業(yè)里，測試設(shè)計工程師跟測試工程師是2個不同職位。前者主要負(fù)責(zé)制定測試策略，添加測試電路，生成測試向量，協(xié)助后者調(diào)通測試程序。后者主要在機(jī)臺上調(diào)通程序，處理量產(chǎn)中測試相關(guān)問題，分析失效原因，協(xié)助其他工藝提高良品率。小點的公司可能2件事情同一個人做，或者干脆由管綜合的人做前者的事情，后者由工廠相關(guān)人員協(xié)助完成。由于大部分公司做的產(chǎn)品可靠性要求不高，所以很多時候只是在芯片上運(yùn)行一下功能測試的程序，不需要做全面的掃描，對測試設(shè)計的專業(yè)性也就沒那么高。另外很多公司甚至沒有量產(chǎn)經(jīng)歷，導(dǎo)致真正水平較高的測試設(shè)計人員很難找到。一般來說做測試設(shè)計的人員都是有過一段時間邏輯電路設(shè)計經(jīng)驗的，測試工程師大部分是半導(dǎo)體廠直接招的畢業(yè)生練出來的。如果有公司要染指利潤，可靠性要求較高的汽車電子，航空電子，最重要的是要有夠水平的測試設(shè)計人員。 數(shù)字電路方面基本就這些崗位，模擬電路的崗位基本也就電路設(shè)計跟版圖設(shè)計，一個電路公司里邊如果有小妞，基本會出現(xiàn)在畫版圖的位置上，不過這些也基本是屌絲女，白富美基本不會光顧這種行業(yè)。下面看看這2種崗位的需求。 Position Description Analog IC designer - responsible for the design and development of analog/mixed signal IC circuit blocks from initial concept/specification through final verification of conformance to customer specifications. Background should demonstrate good problem solving skills, excellent analog aptitude, communication skills, and ability to work cooperatively in a team environment.
