Hi, I teach a basic digital circuit design curse at the university for first-year students. I plan to incorporate HDL, behavioral descriptions, simulation and logic optimization next year. I find Icarus Verilog plus gtkwave and the rest of GEDA tools ideal for the task, but cant find a way to do logic optimization within the geda framework. The icarus 0.8.x README tells logic optimization can be enabled through the "-F" option, but it is not documented in the man page. Logic synthesis to edif works fine but optimization is not applied. Some simple optimization targeting basic logic (AND, OR, NOT) would be ideal for me. Integration in Icarus would be perfect. Do you know of available options within geda or free software. Thanks. -- Jorge Juan
