NanDigits Design Automation

Netlist ECO is very common in large scale IC design. These changes frequently come late in the design process when schedule is tight and where errors are very costly. Netlist changes are error-prone since the netlist is large, complex, unfamiliar, and hard to understand. Manually editing netlist is very easy to make mistakes such as changing the wrong gate or making a typo.

Gates On the Fly, GOF, is designed to solve this problem. It provides both GUI and script modes to change complicated logic. The GUI mode helps you to isolate the logic that needs to change in a partial schematic window so you can easily modify your design. The GUI mode has sharp learning curve for beginners and non-frequent users. The script mode has the same syntax as Perl which can easily integrate existing netlist processing scripts. The script mode is good for more complicated ECO processing, such as combining netlist sanity check and ECO modification.

Gates On the Fly provides the following features:

• Any large size netlist parsing on 64bits Linux platform
• Dynamic partial schematic generation
• Graphical Netlist ECO
• Script Mode Nelist processing and ECO
• Logic Cone ECO to replace whole logic cones
• Save ECO results in several formats
• Integration of commonly used netlist functions
