Tree files are dumps of the AST Tree and are produced between every major
algorithmic stage. An example:
NETLIST 0x90fb00 <e1> {a0}

*1:2: VAR 0x91a780 <e74#> {a22} @dt=0xa2e640(w32) out_wide [O] WIRE
1:2:1: BASICDTYPE 0xa2e640 <e2149> {e24} @dt=this(sw32) integer kwd=integer range=[31:0]
NETLIST 0x90fb00 <e1> {a0ah}
