Abstract: Embodiments herein describe techniques for designing a compressed hardware implementation of a user-designed memory. In one example, a user defines a memory in hardware description language (HDL) with a depth (D) and a width (W). To compress the memory, a synthesizer designs a core memory array representing the user-defined memory. Using addresses, the synthesizer can identify groups of nodes in the array that can be compressed into a memory element. The synthesizer designs input circuitry such as a data replicator and a write enable generator for generating the inputs and control signals for the groups. The synthesizer can then implement the design in an integrated circuit where each group of nodes maps to a single memory element, thereby resulting in a compressed design.
