有办法用一个Xdc命令获取端口0到9位吗？

默认情况下，get_ports（和其他get_ *命令）使用“glob”通配符。
在“glob”通配符中，*表示“任意数量的任何字符”和一个？
意思是“任何一个角色”（+也做了一些事，但我从不使用它）。
因此，你可以使用
get_ports A [？];
＃为0-9位
get_ports A [1？];
＃为10-19位
get_ports（以及其他get_ *命令）可以更改其行为以使用正则表达式而不是glob通配符。
为此，您必须在命令中添加-regexp选项。
然后你可以做muzaffer建议的，但你必须小心“真正的”方形支架。
get_ports -regexp“A  [[0-9] ]”;
＃对于0-9位
get_ports -regexp“A  [1 [0-9] ]”;
＃为10-19位

以下为原文

By default, the get_ports (and other get_* commands) use "glob" wildcarding. In "glob" wildcarding, a * means "any number of any characters" and a ? means "any one character" (The + does something as well, but I never use it).
 
Thus, you can use
 
get_ports A[?];   # for bits 0-9
get_ports A[1?]; # for bits 10-19
 
 
The get_ports (and other get_* commands) can change their behavior to use regular expressions instead of glob wildcarding. To do this, you have to add the -regexp option to the command. Then you can do what muzaffer suggested, but you have to be careful with the "real" square brakets.
 
get_ports -regexp "A[[0-9]]";   # For bits 0-9
get_ports -regexp "A[1[0-9]]"; # for bits 10-19

你可以把它放在一个循环中。
我认为XDC支持主机TCL：for {set i 0} {$ i ... get_ports A [$ i]}另一种选择是使用更受限制的正则表达式。
我想你应该能够说get_ports A [[0-9]。]，即给定列表中的单个字符。
您可能需要进行一些实验，因为我不确定Xilinx在XDC中支持哪种RE实现。

以下为原文

You can put it in a loop. I think XDC support hosts TCL:

for {set i 0} {$i < 10} {incr i} {
    ... get_ports A[$i]
}

Another option is to use a more restricted regular expression. I think you should be able to say
get_ports A[[0-9].]
ie a single character from the given list. You may need to experiment a little bit as I am not sure which RE implementation Xilinx supports in XDC.- Please mark the Answer as "Accept as solution" if information provided is helpful.

非常感谢，你们俩。
它看起来像使用“？”
是一个更好的主意。
是否有任何文档可以在Xdc文件中学习这些语法？谢谢。



以下为原文

Thanks very much, both of you. It looks like using "?" is a better idea.

Is there any document to learn these grammars in Xdc file?

Thanks.

约束记录在UG903中 - 命令列表见附录A.
但是，每个Tcl命令都有帮助信息（类型为“help get_clocks”） - 帮助信息很有用！
但是，XDC约束非常强大，并且很好地了解它们可以让您对设计进行大量控制。
Xilinx有一个很好的课程，用于教授Vivado设计流程和Vivado约束 - 专门针对经验丰富的ISE用户
适用于ISE软件项目导航器用户的Vivado设计套件
适用于ISE软件用户的Vivado Advanced XDC和静态时序分析
这些都是很好的类，真正让您深入了解Vivado，静态时序分析和XDC约束。
Avrum



以下为原文

Constraints are documented in UG903 - the list of commands is shown in Appendix A.
 
Each of the Tcl commands, though, has help information (type "help get_clocks") - the help information is helpful!
 
But, XDC constraints are very powerful, and knowing them well gives you lots of control over your design. Xilinx has a good classes for teaching Vivado design flow and Vivado constraints - specifically aimed at experienced ISE users
 
Vivado Design Suite for ISE Software Project Navigator Users
Vivado Advanced XDC and Static Timing Analysis for ISE Software Users
 
These are good classes and really give you a deep understanding of Vivado, Static Timing Analysis and XDC constraints.

非常感谢，Avrum。

Thanks very much, Avrum.

嗨Avrum，当我尝试在Vivado tcl控制台中输入命令为：get_ports A [？] Vivado给我错误“无效命令名称”？“”。但是当我输入：get_ports A [1？]它确实有效。
为什么呢？谢谢。



以下为原文

Hi Avrum,

When I try to input command in Vivado tcl console as:

get_ports A[?]

Vivado gives me error that "invalid command name "?"".

But when I input:

get_ports A[1?]

It does work. Why?

Thanks.

因为在TCL []中是一个表达式求值器。
解析器试图逃脱它，但显然不是很成功。
它知道1？
开始全球比赛，但由于某种原因通过？
直接到tcl。

以下为原文

Because in TCL [] is an expression evaluator. The parser is trying to escape it but not very successfully apparently. It knows that 1? starts a global match but for some reason passes ? directly to tcl.- Please mark the Answer as "Accept as solution" if information provided is helpful.

嗯，等一下Avrum是否有解决方案。



以下为原文

hmmm, wait to see whether Avrum has the solution for this.

试试“get_port A  [？]”

这确实有效。
非常感谢。我刚才发现Avrum之前曾提到这一点，但我没注意到......



以下为原文

That did work. Thanks very much.

I just found Avrum has mentioned this before, but I did't notice that ……

你也可以把它们放在硬报价中
get_ports {A [？]}
然而，这令人费解。
除非在它之前有空格，否则Tcl解析器不应该看到[作为命令。
它很好用
get_ports A [1]
get_ports A [1？]
我很确定这是一个错误。
我将提交一个webcase。
Avrum



以下为原文

You can also put them in hard quotes
 
get_ports {A[?]}
 
However, that's puzzling. The Tcl parser is not supposed to see the [ as a command unless there is white space before it. Its fine with
 
get_ports A[1]
get_ports A[1?]
 
I am pretty sure that this is a bug. I will file a webcase.
