Hello,

I am listening Low power simulation with IEEE 1801 UPF v22.09 Module 04 : simulating a UPF based low power RTL design
Example of module4 in nano CPU of DebuggingLPS/examples attempted to demonstrate.

However, I tried to run xrun using the example, this error occurred.

I want to solve this problem and demonstrate this example.
