本文档主要介绍了IC设计的验证技术，验证技术的内容较多，也比较复杂，希望这个资料对你们有所帮助

The Secure Digital Card is a flash-based memory card that is specifically designed to meet the security, capacity, performance and environmental requirements inherent in newly emerging audio and video consumer electronic devices. The SD Card includes a copyright protection mech anism that complies with the security of the SDMI standard, and is faster and capable of higher Memory capacity. The SD Card security system uses mutual authentication and a “new cipher algor ithm” to protect from illegal usage of the card content. A non-secured access to the user‘s own content is also available. The physical form factor, pin assignment and data transfer protocol are forward compatible with the SD Card, with some additions. The SD Card communication is based on an advanced nine-pin interface (Clock, Command, 4xData and 3xPower lines) designed to operate in a low voltage range. The communication protocol is defined as part of this specification. The SD Card host interface supports regular MultiMediaCard operation as well. In other words, MultiMediaCard forward compatibility was kept. Actually the main difference between SD Card and MultiMediaCard is the initialization process. The SD Card specifications were originally defined by MEI (Matsushita Electric Company) , Toshiba Corporation and SanDisk Corporation. Currently, the specifications are controlled by the Secure Digital Association (SDA). The SanDisk SD Card was designed to be compatible with the SD Card Physical Specification.

系统在分区时，各分区都不允许跨柱面，即均以柱面为单位，这就是通 常所说的分区粒度。有时候我们分区是输入分区的大小为 7000M，分出来却是 6997M，就是这个原因。 偏移 2H和偏移 6H的扇区和柱面参数中,扇区占 6 位 (bit)，柱面占 10 位(bit)，以偏移 6H为例，其低 6 位用作扇区数的二进制表 示

多媒体卡MMC(MultiMedia Card)是由美国SanDisk 公司和德国Simens 公司于1997 年共 同开发推出的一种多功能存储卡。内置控制电路，可以使用在手机、数码相机、MP3、PDA 等多种数字设备上，可反复记录30 万次。现在市场上的主流容量有128 MB～2 GB。 文中首先介绍单片机对SPI 协议下的MMC 卡的底层读写操作，然后分析MMC 卡文件 系统的结构，最后详细说明MMC 卡文件的创建、读写、删除等操作。该方法可应用到与 Windows 有交互的嵌入式系统中，便于文件的统一管理
