嗨,我有两个问题
首先,在ISE10.1和ISE 13.1中,当我使用FPGA编辑器时,我发现了一个问题。在list1中,我选择了一个网络,然后在array1中我可以看到许多红色线条,它们都是关于这个网络的。然后我触摸工具 菜单并选择延迟,我可以在留言板中看到一些参数,例如 净“CONFIG1_IBUF”: driver - comp.pin“CONFIG1.I”,site.pin“J4.I”1.365ns - comp.pin“N739.F2”,site.pin“SLICE_X4Y37.F3”1.366ns - comp.pin“N739.G2” ,site.pin“SLICE_X4Y37.G3” 我想知道,如果1.365ns'的延迟是否正确,那么与温度的关系是什么? 第二个问题,在spatran 3E中,我可以将完成的引脚连接到3.3V的电源,我将连接完成一个上拉电阻,然后连接到3.3V,这是好的还是必须连接到2.5V? 如果我把它连接到3.3V,那么坏的后果是什么? 以上来自于谷歌翻译 以下为原文 Hi,i have two problem first,in ISE10.1 and ISE 13.1 i find a problem when i use fpga editor.In list1,i choose a net,then in array1 i can see many lines in red,they are all about this net.Then i touch tools of the menu and choose Delay,i can see some parameter in the message board,for example Net "CONFIG1_IBUF": driver - comp.pin "CONFIG1.I", site.pin "J4.I" 1.365ns - comp.pin "N739.F2", site.pin "SLICE_X4Y37.F3" 1.366ns - comp.pin "N739.G2", site.pin "SLICE_X4Y37.G3" i want to know that if the 1.365ns'delay is exactly or not,and what is the relationship with tempreture? second problem,in spatran 3E,can i connect the done pin to 3.3V?of cource i will connect the done to a pullup resistor ,and then to 3.3V,is this OK or must connect it to 2.5V? and if i connect it to 3.3V,what is the bad consequence? |

>我想知道,如果1.365ns'延迟完全与否
报告的值是在所有过程,电压和温度条件下观察到的最大值。 >和温度有什么关系? 它有所不同。 >在spatran 3E中,我可以将完成的引脚连接到3.3V吗? Spartan-3E数据手册DS312将DONE引脚记录为由表46中的2.5V VCCAUX电源供电。将其连接到3.3V而不是2.5V将导致器件损坏。 ------您是否尝试在Google中输入问题? 如果没有,你应该在发布之前。太多结果? 尝试添加网站:www.xilinx.com 以上来自于谷歌翻译 以下为原文 > i want to know that if the 1.365ns'delay is exactly or not The value that is reported is the maximum that will be observed under all process, voltage and temperature conditions. > and what is the relationship with tempreture? It varies. > in spatran 3E,can i connect the done pin to 3.3V? The Spartan-3E data sheet, DS312, documents the DONE pin as powered by the 2.5V VCCAUX supply in Table 46. Connecting this to 3.3V instead of 2.5V will cause damage to the device. ------Have you tried typing your question into Google? If not you should before posting. Too many results?
