EDA Simulation Libraries

[Njoroge]

Could someone please explain how the EDA simlib file works and if possible why it has nearly doubled in size with the latest release? Why would you not need it for the Questa Altera FPGA Edition but need it for regular QuestaSim yet both simulation softwares are roughly the same size?

The EDA simlib file is a critical component in the simulation environment, serving as a library for various electronic design automation (EDA) tools. It contains a collection of pre-compiled simulation models and libraries that facilitate the testing and verification of digital circuits and systems.

The simlib file is typically generated by the EDA tool vendor, Altera, and is specific to a particular tool version and device family. The file contains a set of compiled models, including behavioral models, timing models, and simulation scripts, which are used to simulate the behavior of digital circuits.

Regarding the increase in size of the simlib file with the latest release, there could be several reasons for this:

1. Additional Device Support: The latest release might include support for new devices or families, which would require additional models and libraries, resulting in an increased file size.
2. Enhanced Simulation Capabilities: The new release might include improved simulation algorithms, increased accuracy, or support for new simulation features, which could lead to a larger file size due to the added complexity.
3. Updated Library Content: The simlib file might contain updated library content, such as new IP cores, updated behavioral models, or revised simulation scripts, which could contribute to the increased file size.
4. Changes in Compilation Options: The compilation options used to generate the simlib file might have been modified, resulting in a larger file size. For example, the use of more aggressive optimization options or the inclusion of additional debug information could increase the file size.

Thanks,

Nothing further. Thank you for the help.
