What’s ADHL? I know VHDL and haven’t yet learned Verilog. I once used an old proprietary CPLD language with Lattice (Lattice-HDL???). Very primitive and not particularly easy to use, not to mention too limited for anything beyond little CPLDs.
VHDL and Verilog have the benefit of being standards, and at least for VHDL there are open source tools available (ghdl) that work well.
