ACL2 is a mathematical logic, programming language, and mechanical theorem prover based on the applicative subset of Common Lisp. It is an "industrial-strength" version of the NQTHM or Boyer/Moore theorem prover, and has been used for the formal verification of commercial microprocessors, the Java Virtual Machine, interesting algorithms, and so forth.
Alliance CAD System is a set of EDA tools and portable cell libraries for VLSI design. It covers a wide range of the standard design flow (from VHDL up to layout). It includes a VHDL simulator, RTL synthesis tools, place and route tools, netlist extractor, DRC, and a layout editor.
Balsa is an asynchronous circuit simulation and synthesis system. Balsa is built around the Handshake Circuits methology, and it can generate gate level netlists from high-level descriptions in the Balsa language. Both dual-rail (QDI) and single-rail (bundled data) circuits can be generated.
ChipVault is a chip development program for organizing VHDL and Verilog designs. ChipVault displays designs hierarchically and provides for rapid design navigation and editor launching. ChipVault provides hooks for performing bottom-up tasks such as launching RTL compilers, synthesis, block generation and instantiation, and includes simple to use Revision Control and Issue Tracking systems to help facilitate large group design projects with multiple designers and hundreds of design files. ChipVault is written in Perl and is small, fast, and efficient.
Confluence is a functional programming language for reactive system design, including FPGAs, ASICs, and hard-real-time software. Confluence system descriptions have a large information to linecount ratio. It is typically two to five times more compact than Verilog. Confluence can compile a single body of source code into to Verilog, VHDL, C, and NuSMV.
DOLPHIN SLED is a hierarchical schematic entry solution with graphic linking of components, hierarchical configuration of the netlist, and multi-language netlisting (SPICE, Verilog, VHDL-AMS, etc.). Interoperability with other schematic entry tools, particularly the ECS family (including Synario, Cohesion, and Laker-AMS) is ensured for capitalizing on legacy designs and cooperative work. Interoperability is ensured through standard design exchange formats (EDIF2) and scriptability for customization.
