ibufds_gte2用法ibufds_gte2用法 BUFIO是IO时钟网络,顾名思义,它只能驱动IO Block里面的逻辑,不能驱动CLB里面的LUT,REG等逻辑。BUFIO可以被如下节点驱动: 1、SRCCs and MRCCs in the same clock region 2、MRCCs in an adjacent clock regionusing BUFMRs 3、MMCMs clock outputs 0-3 driving the HPC in ...
我正在尝试在结构中使用GTE时钟。根据架构指南,这就是BUFG_GT的用途。但是对于Vivado 2014.1,当我这样做时:电线wClk156; IBUFDS_GTE3 mIBufDS(.I(iClkP),. IB(i ...
原始IBUFDS_GTE2原语需要在I和IB引脚上插入IBUF才能正确放置。在您的情况下，因为您已将模块设置为OOC...

2. If the IBUFDS_GTE2 is also driving the DRPCLK pin of a number of GTXE2_CHANNEL components directly(for example, six). This sort of connection is not documented, but the IBUFDS_GTE2 can only reach the DRPCLK pin on components in the same clock region by routing thru a BUFHCE. ...
67231 - 2016.2 Vivado IP Flows - Implementing a Block Design (BD) project containing an XDMA MicroBlaze fails with ERROR: [Opt 31-38] IBUFDS_GTE2 (pin name) I pin is connected directly to a top-level port Description I have a project with an IP Integrator block design (BD) that conta...
最近将xilinx官方PCIe end point例子下到VC709中,插上电脑主板时没有任何反应,通过分析原因,发现主板提供的差分时钟在经过IBUFDS_GTE2后无输出时钟(该时钟用于PCIe核)所以导致无link_up上。有没有相关方面大神帮忙分析下。顺便问一下IBUFDS_GTE2是不是坏了(曾自己弄过一个PCB小板子上的晶振产生差分时钟给VC709提供...
Hello,I am wondering if the phase relation between the ODIV output of the IBUFDS_GTE and its input is deterministic or if there is a configuration to have it deterministic? Same question for BUFG_GT, does the O output of the BUFG_GT has a d
While building an OOC module in Vivado using the HD flow, I'm getting this DRC violation and can't find any information about it. ERROR: [Drc 23-20] Rule violation (REQP-1619) IBUFDS_GTE2_driven_by_IBUF - IBUFDS_GTE2 refclk_ibuf pins I and IB should be driven by IBUFs. Looking ...
