Abstract
In described examples, circuitry for saving and restoring a design block state includes first memories configured to receive, and store in different first memories in a first order, different portions of first data; and a second memory coupled to first memories. First memories with the most memory cells have N memory cells. First memories with fewer memory cells have M memory cells. When saving state, first data from different first memories is written in a second order to different corresponding regions of the second memory as second data. The second order repeats portions of the first data stored in sequentially first N mod M cells, determined using the first order, of corresponding first memories with fewer cells. When restoring state, second data is read from the second memory and stored, in the first order, in corresponding first memories; repeated portions are repeatedly stored in corresponding first memories with fewer cells.
