Troubleshoot Poly Fill Generation

Poly fill might not be generated due to various design scenarios and constraints. To generate poly fill correctly, check the following settings:

Ensure that there are no diffusion areas. Poly fill do not fill the diffusion areas.
Check for any spacing rules between diffusion areas and poly shapes. Ensure that these rules are adhered to.
Ensure that the selected area is inside the cellview boundary.
Ensure that the poly shapes are aligned properly along the poly grid. If not aligned, a warning message is displayed and poly fill are not inserted.
Check whether the allowedLengthRanges rule is set for the specified fill layer in the technology file. If set, ensure that the spacing left for the poly fill in the selected area is sufficient to accommodate the poly fill.
