Edge Not on Grid

[Aby]

Hi everyone,
I wrote some skill code to generate a custom power-grid. The grid
appears fine but when I run DRC on it, it gives me errors stating "Edge
not on grid". I think that it may be because the dimensions I compute
in the skill code are not multiples of the manufactuing grid
resoultion. Is there any simple way to fix these errors?

Any comments would be appreciated.

Hi,

f_grid = techGetMfgGridResolution( techGetTechFile( ddGetObj( t_libName ) ) )

where 't_libName' is your technology library name;

returns the mfgGridResolution value form your tech library technology file
which should probably be the right manufacturing gird.

Use the value to calculate your power grid.

Also be careful about paths. Centerlines need to be 2 times the grid or the
edges
end up off grid.
