Error when opening library in Abstract Generator

MSP032

Hi,

I'm getting the below error when opening a library in Abstract Generator. The error is related to an information that should be present in the technology file.

The error says : The routing direction for layer M1 has not been specified. Specify the appropriate direction in the routingDirections sub-section of the layerRules section of the technology file.

The error is coming even though the routing directions are defined in the Technology file.

Please let me know a solution to this problem.

Thanks,
Mallikarjun

  • The question is whether it's in the correct constraint group or the constraint group you're using. Generally the abstract tool uses the constraint group specified as the "Wire" constraint group on the layout editor options form; usually abstracts are generated using the LEFDefaultRouteSpec constraint group.

    It would probably be best to contact customer support so that we can look at the entire tech file setup rather than trying to guess what's wrong from the snippet above.

    Regards,

    Andrew.
