quartus 2 下载问题

quartus 2 中programmer的verify ,blank_check ,examine ,security bit ,erase isp都有什么作用？希望能具体点。

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 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是防止他人导出配置芯片里的文件。
