Specman：如何检索存储在另一个 var 中的 var 值
我已将 var 名称存储在另一个 var 中，并且想从原始 var 中检索值。
例如：
var var_A: list of uint = {1,3,2};
var var_A_str:string = "var_A";
//现在我想使用 var_A_str 打印 var_A 值列表。我怎样才能做到这一点？
print $var_A_str;
I have stored var name in another var and I want to retrieve values from original var.
for ex:
var var_A: list of uint = {1,3,2};
var var_A_str:string = "var_A";
//Now i want to print var_A list of values using var_A_str. How can i do that?
print $var_A_str;

这称为内省或反思。您必须使用 Specman 的
rf_manager。在文档中搜索它。但是，文档并未向您展示该单元具有的所有方法。如果您确实想查看所有方法，请运行此代码片段：我不确定如何迭代列表元素，但您可以使用此代码片段来查看对对象的引用的方法。 /em> 实例成员（不是子例程的变量）。
在我的版本（8.2）中打印：

Checking the test ...我确信有一种方法可以实现您想要的功能，但是使用 Specman 的反射接口可能非常困难。
黑客快乐！
This is called introspection or reflection. You have to use Specman's
rf_manager. Search for it in the docs. However, the docs don't show you all the methods that this unit has. If you really want to see all the methods, run this snippet of code:I'm not sure how to iterate through the list elements, but you can use this snippet to look at the methods on a reference to an object's instance members ( not a subroutine's variable).
In my version ( 8.2 ) this prints:
I'm sure there's a way to do what you want, but it can be very difficult to use Specman's reflection interface.
Merry hacking!
