Abstract :
This paper presents two methods for embedding a watermark to protect intellectual property in a standard-cell layout. The information is added by inserting spaces between placed cells. Our proposed two methods allow the watermark to be added directly to the layout in the spatial domain, or added in the spectral domain using a frequency-domain transform
