I have updated VTx tools with a new module editor. You can see how it 
work at http://www.veriloghdl.org/demo.html
You can see some new technologies, which have never been used by other 
EDA vendors. Through these features, I hope to fulfill the fastest 
framework building tool for verilog and vhdl.
Any comment is appreciated.
