Contents Introduction Discussion Project Proposal Background Information Discussion Logic style sample comparisons Mixed logic circuit design Project Proposal Project time-line

Introduction Mixed Logic Circuits Reason to Use Relatively new area of research Circuits composed of more than one logic type Reason to Use Each logic type has different advantages / disadvantages By implementing two logics, gain advantages of both

Current Trends Industry Trend Research Trend Lower power Higher speed Smaller area Research Trend Recent papers published in mixed logic design Papers focused on PTL / CMOS circuits

Background Standard CMOS Characteristics Most commonly used logic in VLSI design Ease of use, well developed synthesis methods High noise margins Low power consumption No static power dissipation Good current driving capabilities

Background cont’d Pass Transistor Logic Characteristics Widely used alternative to complementary CMOS Fewer transistors are required for a given function Reduced number of transistors means there is lower capacitance Dedicated buffers need to be inserted to boost driving strength

Discussion of Results SCMOS has the best characteristics for low voltage speed and power dissipation No real motivation to develop mixed circuits with these other types of logic

CMOS and PTL

Mixed PTL/CMOS Logic PTL/CMOS logic circuits will be superior Better area, power and delay compared to conventional CMOS or PTL Low power, high performance design driven by PTL cell selection and synthesis technique to produce the mixed structure

Mixed PTL/CMOS Example Pass-transistor/CMOS Collaborated Logic: The Best Of Both Worlds Yamashita, S.; Yano, K.; Sasaki, Y.; Akita, Y.; Chikata, H.; Rikino, K.; Seki, K.; VLSI Circuits, 1997. Digest of Technical Papers., 1997 Symposium on , 12-14 Jun 1997 Page(s): 31 -32 Design assigned selector functions to PTL AND/OR logic functions mapped to CMOS

Design Example Design based on this Boolean equation: Out1 = B * A’ + C * A ( I’ * F’ + D’ ) * ( D + ( H + E’) * ( E + G )) Out2 = B’ + ( I’ + F’ + D’ ) * ( D + ( H + E’) * ( E + G )))’
