vivado中的write bitstream是啥作用

Posted 2023-03-28

参考技术A mcs implement完后.bit" -file x;up 0 E;x:/点一下 generate bitstream setting 勾选里面bin文件产生选项至于产生mcs 方法 我也没找到 似乎是用tcl命令 比如 tcl console里面执行 write_cfgmem -format mcs -interface spix4 -size 128 -loadbit...本回答被提问者采纳

转：进行vivado开发时，Generate Bitstream报错[DRC NSTD-1]，详细解决步骤

报错如下

[Drc 23-20] Rule violation (NSTD-1) Unspecified I/O Standard - 4 out of 142 logical ports use I/O standard (IOSTANDARD) value ‘DEFAULT‘, instead of a user assigned specific value. This may cause I/O contention or incompatibility with the board power or connectivity affecting performance, signal integrity or in extreme cases cause damage to the device or the components to which it is connected. To correct this violation, specify all I/O standards. This design will fail to generate a bitstream unless all logical ports have a user specified I/O standard value defined. To allow bitstream creation with unspecified I/O standard values (not recommended), use this command: set_property SEVERITY {Warning} [get_drc_checks NSTD-1].  NOTE

: When using the Vivado Runs infrastructure (e.g. launch_runs Tcl command), add this command to a .tcl file and add that file as a pre-hook for write_bitstream step for the implementation run. Problem ports: USBIND_0_port_indctl[1:0], USBIND_0_vbus_pwrfault, USBIND_0_vbus_pwrselect.

 

新建记事本，添加以下三句：

set_property SEVERITY {Warning} [get_drc_checks NSTD-1]

set_property SEVERITY {Warning} [get_drc_checks RTSTAT-1]

set_property SEVERITY {Warning} [get_drc_checks UCIO-1]

重命名为  name.tcl文件（确定后缀格式有效）

我用的是vivado2017.4 ，在generate bitstream 界面如下，右键进入setting

 

 

 

 

将新建的.tcl文件添加进来

再一次Generate bitstream  ，大功告成！
