Abstract generator gdsii file import problem

Dinesh Varma4
Dinesh Varma4 over 10 years ago

Hello,

First I exported  File-> export-> stream. and .lef file of inverter designed using cms9flp technology

Once the file were exported then i invoked abstract generator and i gave library, when i was trying to import gdsii file i am getting the following errors.

ERROR ABS-216: There are insufficient metal layers defined in the current design. You must define at least two metal layers in the validLayers subsection ofLEFDefaultRouteSpec constraint group of the technology file. These layers must have the layer function metal in the functions section. Update the technology file and attach it again.

ERROR ABS-218

There are no vias specified in the technology file. Ensure that the selected constraint group has a ValidVias section or at least one via is specified in the standardViaDefs subsection of the viaDefs section in the technology file. In addition, ensure that the function argument is set to 'cut' for the via in the functions subsection of the layerRules section and then try again.

I updated the technology file which was suggested by cadence help but still i am getting the same error

can some one please help me to resolve this error.

I really appreciate your time

Thanks.

DInesh
