Partial reconfiguration of a programmable logic device is used in combination with a shared memory block for communicating between two blocks of an electronic circuit design. In one embodiment, a shared memory is implemented on RAM resources of a field programmable gate array (FPGA), and a first design block implemented in resources of the FPGA is coupled to the shared memory. A second design block is also coupled to the shared memory. In response to a write request by the second design block, a process determines the RAM resources of the FPGA that correspond to the shared memory address in the write request. A configuration bitstream is generated to include configuration data for partial reconfiguration of the FPGA with the data from the write request at the appropriate RAM resources. The FPGA is partially reconfigured with the configuration bitstream via a configuration port of the FPGA.
