I want to run specific parts of the OpenLANE design flow to determine which parameters affect the maximum delay in a design. My plan is to run the placement, routing, CTS (Clock Tree Synthesis), and STA (Static Timing Analysis) processes for the same design but with different parameters.

To achieve this, I'm trying to use OpenLANE's interactive mode. However, I am getting the below error, even though the same commands are mentioned in the documentation. Can anyone help?

have you missed `package require openlane`?

```% prep -design spm
invalid command name "prep"
% package require openlane

Ohkay yes. Sorry, I missed that. Thank you.
