I take contact with Lola many years ago, I'm productive in VHDL so
read about a new description language is mere curiosity.<br>
<br>
<span class="tlid-translation translation" lang="en"><span title=""

Lola is a vendor independent tool, do not export EDIF ?<br>
<br>
EDIF is well supported for vendors tools making easy include Lola
blocks into another design entry flows.

Thanks for your feedback.

I would not recommend to sidestep the synthesis tool. The question would then be: who would do the logic minimizations/optimizations and the technology mapping? 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.
