Abstract
Pass Transistor Logic (PTL) circuits have been successfully used
to implement digital ICs which are smaller, faster, and more en­
ergy efficient that static CMOS implementations of the same de­
signs. Thus far, most PTL implementations have been handcrafted;
as such, designer acceptance of PTL has been limited. In this
paper, we develop efficient algorithms for automated synthesis of
high quality PTL designs. Our approach is based on the use of Bi­
nary Decision Diagrams (BDDs) to represent logic functions. We
present several BDD optimization techniques targeting minimum
area PTL implementations. We compare our results with prior work
