Thanks David,

I am putting below the parts that Arturo mentioned should go into list of future enhancements.

Regards,
Sandeep.

Section 20.6

There is no way to specify global options applicable to all the covergroups.

Suggestion: Add syntax to define global options applicable to all covergroups. For example,

global_covergroup_options.auto_bin_max = 100;

Section 20

In order to separate the design and verification efforts, it should be possible for a user to write the coverage model independent
of the design and then bind it to the design. The features binding properties to a module/instance are explained in the section on
assertions, using the bind construct. The bind construct should be extended to allow binding of coverage model to modules/instances.

Section 20

Extensions to VPI would be required to access the covergroup definitions, instances and details. It should be possible to iterate
over covergroup definitions/instances in a scope, coverpoints/bins/crosses/transitions in a covergroup and their details.

Since a hierarchical scope is created all the way upto a bin, the following piece of code (or something similar),

hdl = vpi_handle_by_name("top.i1.c11.A.auto[0]", 0);
vpi_get_value(hdl, value_p);

should work and return the coverage count or coverage value of the specified object.

These ideas are well motivated. However, I believe it is too late to add new functionality to this version.

I propose we add this request to the list of future enhancements.

It is now time to do so. Can you please send me an email with just the enhancement requests you would like to see so that I can add
them to the Future enhancements list we keep on the reflector?
