Design compiler read_db

  • What is .DB file in VLSI?

    db formatted library where all the cells are in a single binary file.
    With a . db library, the entire library has to be read into memory.
    In the Milkyway Environment, the Synopsys tool loads the library data relevant to the design as needed, reducing memory usage..

Do I need a library-compiler license to convert lib to DB?

You 'll need a library-compiler license to convert .lib to a .db with functional description.
However for black-box translation with timing parameter only, the error message complaining no LC license can be ignored.
The .db still works, who cares.. dont have a library compiler license.
Not open for further replies.

How do I read a db file into design compiler?

For a .db file to be read into Design Compiler, its file version must be the same as or earlier than the version of Design Compiler you are running.
If you attempt to read in a .db file generated by a Design Compiler version that is later than the Design Compiler version you are using, an error message appears.

How does design compiler read the Alib file during compile?

Design Compiler reads the ALIB file during compile.
The ALIB file provides Design Compiler with greater flexibility and a larger solution space to explore more intelligent tradeoffs between area and delay during optimization.
You must use the compile_ultracommand to get the benefits from the ALIB library.
