help: where is "LE" or "LUT" component (or "how do I create my own components?")

About the schematic v.s. HDL topic :

I switched from schematic to Verilog and love it because ...

MODELSIM! A huge pain to learn. Essential once you get used to it.

Portability. Schematic is too vendor specific. Worry that it might stop working in a few years, etc.

You can generate Verilog easily with C / scripts, etc. It is clear that with Verilog entry and a C compiler in the background I can make any circuit I want and my hand won't fall off from clicking.

I do fiddle with schematics on paper while designing / optimizing / thinking. For what it's worth.
