in UVM, how to change the description of type coverage

To change the description of a type coverage in UVM, you can use the set_type_cov_description() function provided by the uvm_coverage class. This function takes two arguments: the name of the type coverage and the new description string.

Here is an example code snippet:

uvm_coverage my_type_cov;
string new_desc = "This is a new description for my type coverage";

// Set the description of the type coverage
my_type_cov.set_type_cov_description("my_type_cov", new_desc);

This will update the description of the type coverage named "my_type_cov" to the new description string provided.
