is an experimental software tool to perform behavioral transformations of designs specified on algorithmic and behavioral levels. TDS transforms the initial design specifications into a data flow graph (DFG) optimized for a particular objective (latency, resource utilization, etc.) prior to high-level synthesis. The behavioral transformations are based on graph-based canonical representation, Taylor Expansion Diagram (TED), followed by structural transformations of the resulting DFG network.
Thanks to canonicity of the TED representation, the system can be also used for equivalence checking of designs specified in C or behavioral HDL.
The system is intended for data-flow and computation-intensive designs used in digital signal processing applications.

- BDS (BDD-based Logic Synthesis system)
is our fast and efficient logic synthesis tool, based on a novel theory
of BDD-based bi-decomposition.
It provides both algebraic and Boolean decomposition of several types:
AND, OR, XOR, and MUX.
It handles random and control logic (AND-OR intensive) functions
as well as arithmetic (XOR-intensive) functions.
Its unique approach to partitioned BDD's allows it to handle very large
circuits. Version BDS-1.2 is now available from the following link:
