I was running the riscv model with default setup. When I was trying to find wns for hold after the full run (or in cts, route). It is returning as INF.

Command:
```

report_worst_slack -min

```
Returns `worst slack INF`

**pdk:** asap7
**design:** riscv32i

Any idea why is that and how to solve it?

### maliberty
In which PDK?  How did you load the design?  Please give specific steps to reproduce the issue.

### maliberty
I guess you meant ```make gui_6_final.odb``` without the 'e'.  I get:

```

>>> report_worst_slack -min

worst slack 40.29

```
