Building Ben's 8-bit CPU in VHDL (to learn a bit about FPGAs). Baby Step 1: Clock Module...
I started such a project in VeriLog once, if you want a reference. I abandoned it before getting to branches, however, in favor of writing a 6502 implementation.

Why define LUTs and ROMs directly?
My sample CPU is an implementation of Ben Eater's 8-bit machine. You can see it at https://github.com/CompuSAR/Ben8Bit.

Why define LUTs and ROMs directly?
I was trying to debug the 65c02 code at https://github.com/Arlet/verilog-65c02 on the Spartan-7. The code itself directly defines a lot of LUTs, as well as encode logic in ROM by directly defining a ROM and dumping a bunch of binary data into it.
What are some alternatives?
