readme.txt Usage: Use the 74hc193.asy assembly file in your circuit designs along with a .param statement as discribed below Each gate has a tdgate, and D flip flop has a tdgate2, time delay (td) in value2 line. Each gate and flip flop has a vhighgate voltage value for logic high. Each gate and flip flop has a vlowgate voltage value for logic low. One way to assign these values is through a .param statement in main circuit (74hc193_test.asc for example). 74hc193.asc component requires:TnotSRFlipFlopfromD.asc and TnotSRFlipFlopfromD.asy files to work.
