RE: [sv-cc] cbValueChange on SV String

Sorry for my mistakes.
Of course should be : "opposite to" in place of "oposite do"

Ok. 
But don't You think that strings in oposite do class object  should have
possibility to set cbValueChange on them?
If I change string value into null that is also a value. This is different
situation  then it is with i.e dynamic array members.

Probably because a string data type is a type of dynamic array.

Hi 

I'd like to ask about callback's on SystemVerilog string.

 

LRM says:

 

"cbValueChange After value change on some variables, any expression, or
terminal or after

execution of an event statement. Specifically excluded are class objects,
dynamic

arrays, strings, queues, and associative arrays."

 

Is there as reason why callback cbValueChange cannot be set on string?

 

example:

string s="a";

if I set cb on value change I can detect :

 

s="b"

 

were size is still the same 

 

BTW: LRM 1800-2009 on page 1022 have bug:

"For a cbValueChange callback, if the obj has the vpiArrayMenber property
set to TRUE" 

 

 

Regards,

Radek
