Hello all, I appreciate any time you take to read this.

I'm somewhat new to KiCAD and new to using simulation software's. I cobbled together some SPICE code for the parts in the circuit below and ran the ERC to try and knock down any errors.

The simulation still does not run. I am trying to model the transient voltage spike during the 'turn on' of the PCB and the output waveform. This is V2 and previous versions (not made by me) had issues with hot chips, damage and inconsistent output voltage and current. My version adds filtering capacitors according to the recommended circuit noted on the AL8860 data sheet. Note: I used power flags because grounds were giving ERC errors.

See attached zip file for content (pictured schematic is found in the 'Simulation Schematic folder).
Any feedback on the PCB construction is appreciated as well.
