数字电路方面基本就这些岗位,模拟电路的岗位基本也就电路设计跟版图设计,一个电路公司里边如果有小妞,基本会出现在画版图的位置上,不过这些也基本是屌丝女,白富美基本不会光顾这种行业。下面看看这2种岗位的需求。
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. The candidate would become part of analog IC design team creating leading edge IP (ADC's; DAC's; PLL's; SerDes) in leading edge processes (28nm and below).
Position Requirements
Must be familiar with design concepts for some basic analog functions including some of the following: data conversion, switched-capacitor circuits, op-amps, comparators, voltage and current references, phase-locked loops. Must be proficient in using CAD tools for circuit simulation, verification, and layout. 2-3 years employment or intern epxerience. Postion is also open to high performing recent EE graduate who has completed coursework that includes analog design.
版图工程师
Key Areas of Responsibility:
• Technical tasks involved are full customer layout design, layout check and verification.
Required knowledge, skills, abilities:
• Understanding the basic process and device knowledge. It is preferred to have knowledge on HV process/device.
• Familiar with layout tools, verification tools, command file based on cadence environment.
Additional knowledge, skills, abilities, certifications:
• Understanding basic IC design knowledge, especially in analog IC. Knowing of ESD and latch-up related will be considered a plus.
Required education and experience:
• At least Bachelor degree is required. More than one year of prior experience in full-custom –design analog IC layout is necessary. Layout experience in Power management IC with HV process is preferred.
现在画模拟版图电路基本都是cds的输入仿真工具,外加mentor的验证工具,现在模拟电路设计基本停留在cad阶段,eda还处在概念期,所以对人员经验要求较高。很多公司对有经验的电路工程师的定义是8年以上,可见这个岗位成才挺慢。做模拟电路需要对电路理论,半导体制程都有些了解,如果做高频电路,还要懂电磁波跟信号处理方面的东西,这些东西上大学期间不要说学生能够完全搞清楚的没几个,即使大部分教这些课程的叫兽僵尸,也只不过能把课本念熟练,真正完全理解的也不多见。所以真正有水平的模拟电路设计师,尤其是射频集成电路设计的,即使世界范围内也是稀缺资源。当然国内现在也有不少在做模拟电路的,但是大部分是做电源管理芯片,这个大概算模拟电路中的入门产品吧,甚至有些小公司直接翻抄版图,也能出些产品。整体来说,这个岗位属于需求大于供给的,即使水平一般,也不愁没地方工作,除非闹经济危机所有公司都裁员的时候。这个工作如果能把需要学的都完全搞明白了,其实劳动量也就是算一下电路参数,做个仿真,指导一下版图,属于所有岗位里最轻松的,不过想能搞明白电路各种参量的关系,也绝非易事。
画模拟版图的貌似跟电路设计正好相反,很多新招聘的版图员甚至不知道啥是三极管,然后被培训几天后就练习抄版图,然后熟练了逐渐自己设计。这个职位基本只要明白各层次之间关系,不是色盲,手脚够快,基本就能很快上手。不过这个职位也是所有职位里边最辛苦的,要看着花花绿绿的显示器不停的调整各个线条,而且版图设计时间压力一般也很大。一些私营公司的画图小妹甚至会被老板骂哭。这个职位可以说是最有屌丝气息的一岗位,当然如果熬出来收入也还不错,只是这个活计实在太费眼。
现在大部分电路都是数模混合,全芯片整合用数字设计流程,所以很多模拟电路设计都是设计模块,然后集成进芯片,由于模拟部分尚且没有标准的验证流程,也不能像数字电路那样放进fpga先跑跑看,而且模拟电路的测试设计也没有明确规范,所以集成在一起的芯片大部分问题是由于模拟电路部分。相信随着设计方法的改善与分工的细化,模拟电路方向会有更复杂的分工。
电路公司里边其他职位,基本都是跟软件或者整个系统相关了,这里就先介绍这些吧。对于其他的,如果有人比较了解,欢迎补充。之后我想整理一些对工作学习有帮助的网址,不知道是否有人有兴趣
