[Oberon] LolaCreator: a Lola-2 IDE based on Qt Creator

I take contact with Lola many years ago, I'm productive in VHDL so read 
about a new description language is mere curiosity.

This curiosity leads me to ask why, as Lola is a vendor independent 
tool, do not export EDIF ?

EDIF is well supported for vendors tools making easy include Lola blocks 
into another design entry flows.

These things would then have to be implemented in the Lola compiler. Refering to the argument of Wojciech Skulski Lola-2 has behavioral/algorithmic constructs (a decent and presumably sufficient subset of Verilog), and I'm not even sure whether it would be possible to specify a design with Lola-2 only on gate or structural level. The Verilog the Lola-2 compiler generates is still on behavioural level, not just a minimized RTL netlist using the cell types of the target architecture. If we wanted to produce such output, we would have to implement most features of Yosys in the Lola compiler.
