Abstract — In this paper we present a TL specific synthesis tool that aims to exploit the specific characteristics of TL gates, especially the possibility to assign weights larger than one to TL gate inputs. Moreover, instead of confining network nodes with input fan-in restriction, we employ the sum of weights as constraint, as this is more relevant to the physical basis of TL implementations. To make a seamless concatenation with Boolean logic network access and synthesis, we embedded our program into a widely applied existing logic synthesis tool, SIS from University of Berkeley, by supplementing it with 8 new TL specific commands. Several efficient heuristic synthesis methodologies are proposed, tested, and implemented, and the user can change the synthesis approach by simply specifying the required heuristic. To evaluate the proposed tool we used 22 MCNC benchmark circuits. Our experiments suggest that when compared with the state of the art our system can achieve, on average, a 24.5 % node count reduction (area), a 32.8 % network depth reduction (delay), and a 49.4 % product of node count and network depth (area delay product) reduction. Furthermore, our tool is able to provide well-balance networks, which is highly important for practical designs.
