illegal_bins in Functional coverage?

[mssajwan]

Hello Friends,

I have a doubt about the coverage point.

Can we define illegal_bins = default in a coverpoint.

Suppose i have a one vector reg [2:0] check;
Can i write the coverpoint like this
coverpoint check{
bins check_value[] ={3'b001,3,b010,3,b100};
illegal_bins = default;
}
I want to display the error message anytime illegal bin occurs. If this is not possible
then what can be a possible workaround?
If illegal_bins can not be defined as default then what about ignore_bins? Can they be defined as default?


Thanks
Manmohan
