High volume USB 2.0 devices will be designed using ASIC technology with embedded USB 2.0 support. For full-speed USB devices the operating frequency was low enough to allow data recovery to be handled in a vendors VHDL code, with the ASIC vendor providing only a simple level translator to meet the USB signaling requirements. Today s gate arrays operate comfortably between 30 and 60 MHz. With USB 2.0 signaling running at hundreds of MHz, the existing design methodology must change.

我用DELPHI写的一个专为EZUSB（2131）系列芯片的DLL。有例子-I used to write an ad for EZUSB (2131) series chip DLL. Examples are

该工具用于数字电路仿真中的usb数据文件转换： 1.可以把11比特的令牌包数据（crc5）或者任意字节的数据包数据（crc16）转换为可以作为仿真输入的dn dp文件。 2.可以根据仿真接收到的dn,dp数据，解析得到接收的真正11比特令牌包数据或者数据包数据。 3.此为0.1版本，后续的版本更新会让该工具更完善。-The tool for digital circuit simulation usb data file conversion: 1. Can be 11-bit token packet data (crc5) arbitrary bytes of data or packet data (crc16) conversion could serve as a simulation input file dn dp. 2. Can be received in accordance with simulation dn, dp data analysis to be receiving the real 11-bit token packet data or packet data. 3. This is the 0.1 version update will follow-up version of the tool even better.
