ABSTRACT:
In one aspect of the invention, a circuit for generating addresses for memory initialization within a programmable logic device (PLD) is provided. The circuit includes input registers, which are loaded and unloaded with data triggered by the edge of a clock. The circuit further includes multiplexers, where the multiplexers are capable of receiving output of the input registers and encoded programmable addresses. The multiplexer generates encoded row addresses for a wordline of a memory within the PLD. The circuit includes a decoder to decode the encoded row addresses for the wordline of the memory.
