MVSIS: Logic Synthesis and Verification

This makes functionally-reduced AIGs very useful in a variety of applications in synthesis and verification, and ABC a system possessing unique characteristics not available in other tools.

Because of this, manyof the simulation capabilities of Verilog cannot be supported by synthesis.

Moreover, the sequential synthesis results are sequentially verifiable using an independent inductive prover similar to that used for synthesis, with guaranteed completeness.

The figure below shows the general style of a synthesizeable Verilogcombinational logic block.

We have developed an incremental placement algorithm that can be used in avariety of placement-aware logic synthesis methods. Given a point placement ofa network, using the algorithm it is easy to compute the optimum location for anewly introduced node that minimizes the total increase in half-perimeterwire-length of the placement. We have applied this algorithm to placement-awarecommon divisor extraction where the goal is to reduce the congestion duringrouting. Our experiments on industrial and academic test-cases show that thistechnique significantly reduces congestion.

It contains the basic data structures with limited synthesis and verification options.

Topics of interest include, but are not limited to: hardwaresynthesis and optimization; software synthesis; hardware/softwareco-synthesis; power and timing analysis; testing, validation andverification; synthesis for reconfigurable architectures; hardwarecompilation for domain-specific languages; designexperiences. Submissions on modeling, analysis and synthesis foremerging technologies and platforms are particularly encouraged.

ABC combines fast scalable logic optimization based on And-Inverter Graphs (AIG) with innovative algorithms for integrated sequential optimization and verification.

Another fundamental premise of ABC is the synergy between synthesis and verification achieved by recording synthesis operations using an AIG database and enabling efficient SAT-based verification relying on the advantageous properties of AIGs.

Lab 8 - Combinational Logic Design using Verilog and Synthesis

In addition to algorithms for multi-valued logic, MVSIS includes fast binary synthesis algorithms, technology mapping and resynthesis proceduresand state-of-the-art engines for combinational and sequential equivalence checking. There are stand-alone binaries for Windows and Linux that you candownload from the link on the left.

Most of the algorithms developed by our group are incorporated in an open-source program called MVSIS which is the successor of the SIS program,also developed here at Berkeley. Although the initial focus of MVSIS wason logic minimization for multivalued networks, over time it has developedinto a full featured tool for synthesis and verification in general.
