quartus中往FPGA烧程序，在AS模式下，烧写文件是pof吧？后面的那些选项如verify等，哪些需要勾上？

AS模式下 烧写pof文件需要注意的是在setting/device and pin option中选择configuration这个里面configuration scheme选择ASconfiguration device选择你配置芯片的型号（EPCS4这样唯档汪的)。

JTAG模式 烧写SOF文件。

2种蠢掘模式下首先指仔需要确定电路和物理连接的正确然后继续。在hardware setup中选择usb。一般勾上Program/Configure就可以了。

最近也遇到这个问题，以下的内容来自Altera的官方帮助网页。

Specifies the following optional tasks:

Program/Configure— Programs data loaded from one or more programming files or an examined device onto one or more blank (or erased) devices.

Verify— Verifies the contents of a programmed device against programming data loaded from a programming file or an examined device.

Blank-Check— Examines one or more devices to ensure that each is blank or completely erased.

Examine— Loads the programming data from a device into a temporary data buffer. You can examine only one device in a chain at a time. This option is mutually exclusive of all other options for that device and all other devices in the chain. When this option is turned on, all other device options are unavailable. You must save programming data from examined devices before you save the Chain Description File (.cdf). Save programming data for an examined device by selecting the device and clicking Save File 搏判in the Programmer.

Security Bit— Prevents a device from being examined and inadvertently reprogrammed. Only MAX 3000 and MAX 7000 devices use this option.

Erase— Erases content from MAX II devices.

ISP Clamp—Allows you to use the Quartus II software to hold each I/O pin of a device to a static state when you program the device.

简单来说，Verify是验证FPGA配置芯片里的颤枯程序与烧写的文件是否一致。Blank-Check是检查配置芯片是否为空。Examine可将配置芯片内的内容导出成文件。Security Bit是防止他人导出基洞改配置芯片里的文件。

quartus链接不上烧写桥纳橘器原因：

1、写片器也较编程器故障。敏团

2、写片器和PC通信故障。

3、单片机芯片故障。

4、写片器驱动程序不正确。

5、烧录程序选择的单片机型号不正确。

6、程序编译茄稿如果不正确，即使烧录进单片机，也不能正常工作。
