These decap cells were redesigned to cut back on its use of the LI layer because the corresponding SkyWater cell was covered in something like 70-80% LI, and using enough of the decap in any one design would cause an LI density error. | |
The fill cells were redesigned to add tap diffusion in the middle because otherwise the spacing of the nwells and the height of the cells prevents FOM fill, resulting in a different density error. |
