Troubleshoot Minimum Width Value Issues

Abstract Generator checks the minWidth values specified for all the metal layers in the design and issues an error message ABS-10023 if the value is undefined or is 0.

Abstract Generator issues an error message ABS-10022 if the minWidth value is not a multiple of the manufacturing grid for a particular layer. This check is performed only if there is a manufacturing grid value defined in the technology file.

ABS-10023

The '%s' layer does not have a minimum width. Define in the spacings section of foundry constraint group of the technology file and then try again.

ABS-10022

Layer name spacing value is not a multiple of the current manufacturing grid value. The width, pitch, separation, and offset values of all metal layers must be a multiple of the current manufacturing grid value. Update the spacing value for this layer in the spacing section of the foundry constraint group and the routingGrid section of the LefDefaultRouteSpec constraint group in the technology file.

ABS-10010

Manufacturing grid value is not specified in the technology file for the '%s' value. Define the manufacturing grid value in the Physical Rules section of the technology file before you run the abstract generator.

ABS-10028

The routing offset value for a layer must be equal to that of the equivalent base layer; for example, metal2 or metal1, depending on which layer is being examined. Use the Technology File Manager to define the offset value in the LEFDefaultRouteSpec constraint group of the technology file.
