Free RTL-GDSII Flow ?


Is the are back-end P&R software that is either open-source or free for back-end design ?

icarus can be used for simulation
gtkwave for viewing waves
limited synthesis can be done with icarus with scripts to convert it to technology libraries

but from a netlist to placed routed gates, is there any open-source or free software that can do that ?
