Subject: Re: [sv-ec] open-ended ranges 

 

When I tried a search I also found '$' references in many places of LRM.

For coverage purpose, I think, 8.19, 18.5 & A.10.20 are sufficient.

In 8.19, I found the following text which tells us how to calculate the

range bounds for $.

"A bound specified by $ shall represent the lowest or highest value for
the type of the expression on the left-hand side."

From A.10.20, it appears that '$' cannot be specified as single value
for bins. For example,

bins b1[] = {[3:4], $, 9} is not legal. Is it correct? Also should we
allow [$:$] for bin ranges?

I see no issue as it is just another way of specifying the complete
value range for a variable.

 

Thx,

Swapnajit.

	I think the complete set of sections where $ is described in its
different uses is:

	 

	5.14

	 

	6.3.2.1

	 

	8.19

	 

	17.5

	17.6

	17.7.2

	 

	18.4

	18.5

	 

	22.4

	 

	A.2.5

	A.2.10

	A.8.4

	A.10.20

	A.10.22

	Well, first it is somewhat described just before 18.5.1.

	 

	But see 6.3.2.1 and particularly 8.19.

	It is described in LRM that open-ended ranges can be 

	specified for coverbins. But I coudn't find the exact 

	semantic of this syntax in the LRM. 

	 

	For example,

	[$:5] => what this means for a coverpoint of 3bit size ?

	[5:$] => what this means for a coverpoint of 3bit size ?

	 

	Does it exist somewhere in the LRM? I have seen

	it in queues chapter. But that's not exactly what I

	am looking for.

	 

	Thx,

	Swapnaji
