In this paper, we describe the generation method of interface logic which replace between IP & IP handshaking signal with asynchronous logic circuit. Especially, we suggest the new asynchronous sequential "Waveform to VHDL" code creation algorithm by flow chart conversion : Wave2VHDL - if only mixed asynchronous timing waveform is presented the level type input and pulse type input for handshaking, we convert waveform to flowchart and then replace with VHDL code according to converted flowchart. Also, we confirmed that asynchronous electronic circuits are created by applying extracted VHDL source code from suggest algorithm to conventional domestic/abroad CAD Tool, Finally, we assured the simulation result and the suggest timing diagram are identical.

We propose here sequential 2 methods for obtain information of current or potential data for power transmission line. One is a digital data transmission unit, this is, an output of a current sensor of power transmission line is digitalized by use of an easy asynchronous protocol. The unit has high speed transform rate, easy making header caused of consisting of only logic circuit. The other is, the output of the unit is transformed via LAN interface and displayed on a personal computer. We have confirmed remote measuring using the method for 100A and 240 A of the current information of power transmission line. Therefore we will be able to see a current waveform by use of internet at a cheep c...
