LCD仿真器是一种电子产品的辅助开发工具。目前LCD（液晶屏）在各种电子产品的使用越来越广泛，开发人员在开发带LCD的产品时会用到各种各样的LCD，这些LCD或是现有的，或是定制，现有的LCD不一定能完全满足设计需要，定制LCD需要时间，需要资金，做好后还有修改的可能性，造成不必要的浪费。传统的做法是用LED（发光管）＋驱动电路来仿真LCD，其弊端有四，一、电路复杂，功耗大，100多点的LCD电流将达1A左右。二、图案逼真性差，不直观。三、制作、修改困难，灵活性差。四、通用性不强。 LCD仿真器完全克服了以上存在的问题，她采用软硬件结合的方法，充分发挥软件在作图、运算方面的优势，使仿真的图案与目标LCD图案完全一致，仿真LCD特性与目标LCD特性几乎一样，并提供强大的LCD图形编辑工具，对于不同的LCD产品，LCD仿真器硬件不必更换，只需制作不同的LCD图案，她的灵活性、通用性将是您开发LCD产品的理想选择。 LCD仿真器由采样板、仿真软件和LCD图形编辑软件组成，采样板通过USB口与PC机通信。 LCD仿真器可以方便地与HT1621、Winbond、SAMSUNG，中颖、十速HOLTEK、义隆等带LCD DRIVER的单片机连接。

This white paper discusses how market trends, the need for increased productivity, and new legislation have accelerated the use of safety systems in industrial machinery. This TÜV-qualified FPGA design methodology is changing the paradigms of safety designs and will greatly reduce development effort, system complexity, and time to market. This allows FPGA users to design their own customized safety controllers and provides a significant competitive advantage over traditional microcontroller or ASIC-based designs. Introduction The basic motivation of deploying functional safety systems is to ensure safe operation as well as safe behavior in cases of failure. Examples of functional safety systems include train brakes, proximity sensors for hazardous areas around machines such as fast-moving robots, and distributed control systems in process automation equipment such as those used in petrochemical plants. The International Electrotechnical Commission’s standard, IEC 61508: “Functional safety of electrical/electronic/programmable electronic safety-related systems,” is understood as the standard for designing safety systems for electrical, electronic, and programmable electronic (E/E/PE) equipment. This standard was developed in the mid-1980s and has been revised several times to cover the technical advances in various industries. In addition, derivative standards have been developed for specific markets and applications that prescribe the particular requirements on functional safety systems in these industry applications. Example applications include process automation (IEC 61511), machine automation (IEC 62061), transportation (railway EN 50128), medical (IEC 62304), automotive (ISO 26262), power generation, distribution, and transportation. 图Figure 1.
