how to view toggle coverage with vcs

Hi, all,

I was try to get good toggle coverage for my design!!!
Here were some reports from VCS

-----------------------------------------
MODULE top.mydesign.sub_design_1

// Net Coverage

// Name Toggled 1->0 0->1
mpu_addr[5:0] Yes
\n282!2!4 No No No
\n282!1!0 No No No
\n282!2!3 No No No
\n282!2!2 No No No
\n282!2!1 No No No
.............
.............
..............

-------------------------------------------

I would like to know if any easier way to trace the unmeaning nets
were function related to meaning nets??? Or I can only trace from netlist one by one???

Thank you for advise

Hi,
Does your netlist contain nets named \n282!2!1 etc.? If so, it is likely that your synthesis tool generated these "escaped identifiers" and I don't see any value in trying to get VCS fix this - either write a perl script to do search-replace or even better, define your synthesis naming rules inside DC and use it.
