I understand your issue is that the variable 'p1' cannot be traced when you run the simulation. This could be because the variable is not assigned or defined in the Simulink model. To resolve the issue a few possible steps are mentioned below.
- Find if there is any assignment of 'p1' within the blocks. If not, a value needs to be assigned to the variable.
- If 'p1' is being used as an input or output to a block, it needs to be ensured that it is properly connected to the block.
Hope this helps in resolving the issue.
