How to analyze pin accessibility?

archive

Hello everybody,

I am starting to work on the second rev of an hard IP and based on the first rev issues I believe I might have some pin accessibility issue on standard cells and some large macros.

Can anyone share how you find those? Is FE having any capability to analyze LEF models and report pins with bad accessibility either cell by cell or in a placed design.

Thanks in advance for your help,
Eric.

  • Hello there !!
    check the below command for pin accessibility issue ,
    The following command checks the floorplan and generates a text version of the report called checkDesign.rpt
    NAME : " checkDesign"
    Examples
    checkDesign -physicalLibrary -noHtml -outfile checkDesign.rpt

    The above command also checks for missing or inconsistent Physical library (LEF) The software
    generates error messages for the following conditions:
    - Cells not defined in LEF
    - Cells with missing dimensions
    - Pins with missing direction
    - Cells pins with missing geometry
    - Cell dimensions are not an integer multiple of the core site dimensions
