可编程逻辑器件下载线
摘要：
一种可编程逻辑器件下载线，包括一并行接口及一用于连接可编程逻辑器件的烧录接口，所述并行接口和烧录接口之间连接一逻辑控制电路，所述逻辑控制电路包括一第一组和一第二组传输通道及分别对应控制所述第一组和第二组传输通道导通与否的第一和第二开关组，所述第一组和第二组传输通道导通时分别将所述并行接口的针脚与所述烧录接口的针脚以不同的对应方式导通。上述可编程逻辑器件下载线根据不同公司的可编程逻辑器件规格以提供一组对应的传输通道将所述并行接口与所述烧录接口连接，使所述可编程逻辑器件下载线可满足多种不同规格的可编程逻辑器件的烧录需要。
摘要（英）：

The invention relates to a loading wire of a programmable logic device, which comprises a parallel interface and a recordable interface. A logic control circuit is connected between the parallel interface and the recordable interface and comprises a first set of transmission passages, a second set of transmission passages as well as a first switch set and a second switch set which correspondinglycontrol the first set of transmission passages and the second set of transmission passages. When being conducted, the first set of transmission passages and the second set of transmission passages respectively conduct the pin of the parallel interface and the pin of the recordable interface in different corresponding modes. The loading wire of a programmable logic device provides a set of corresponding transmission passages to connect the parallel interface with the recordable interface according to the sizes of programmable logic devices of different companies to satisfy the recordable requirements of programmable logic devices of different sizes.
