Re: A small Lisp-Machine in an FPGA

The verilog code had been poorly written. For example, it's not common for a combinational circuit to have an input reset. Latches are inferred in some places that can cause unexpected behavior. That's just my observation though. It's cool to see projects like this. Sadly, it appears to be inactive after seeing the project log.

Could you link to an example?

There's only one example there. http://www.aviduratas.de/lisp/lispmfpga/code.html

What's a really well written OSS Verilog example? Trying to switch from embedded to RTL design here.
