A Partial-Mask SRAM Object file (.pmsf) is an intermediate file format that represents a partial reconfiguration bitstream. The .pmsf contains aggregated Mask Settings File (.msf) and SRAM Object file (.sof) data required to generate apartial reconfiguration bitstream Raw Binary file (.rbf).
A .pmsf is generated with the Convert Programming Files dialog box, or from the command line by typing quartus_cpf-p.The .pmsf is used to generate a partial reconfiguration bitstream Raw Binary file (.rbf) with the Convert Programming Files dialog box. Each PR region requires a .pmsf file for each of its implementations.
