netgen

Automatic 3d tetrahedral mesh generator

NETGEN is an automatic 3d tetrahedral mesh generator. It accepts input from constructive solid geometry (CSG) or boundary representation (BRep) from STL file format. NETGEN contains modules for mesh optimization and hierarchical mesh refinement.

netgen-lvs

Netlist comparison - Layout vs Schematic (LVS)

Netgen is a tool for comparing netlists, a process known as LVS, which stands for "Layout vs. Schematic". This is an important step in the integrated circuit design flow, ensuring that the geometry that has been laid out matches the expected circuit. Very small circuits can bypass this step by confirming circuit operation through extraction and simulation. Very large digital circuits are usually generated by tools from high-level descriptions, using compilers that ensure the correct layout geometry. The greatest need for LVS is in large analog or mixed-signal circuits that cannot be simulated in reasonable time. Note that the executable name in Debian is 'netgen-lvs'. For details, see /usr/share/doc/netgen-lvs/README.Debian

qflow

Open-Source Digital Synthesis Flow

This is a complete tool chain for synthesizing digital circuits starting from verilog source and ending in physical layout for a specific target fabrication process. In the world of commercial electronics, digital synthesis with a target application of a chip design is usually bundled into large EDA software systems. As commercial electronics designers need to maintain cutting-edge performance, these commercial toolchains get more and more expensive, and have largely priced themselves out of all but the established integrated circuit manufacturers. This leaves an unfortunate gap where startup companies and small businesses cannot afford to do any sort of integrated circuit design. Qflow tries to fill this gap.
