ID:11959 Can't open Technology Map Viewer (Post-Mapping) -- post-mapping atom netlist not available

CAUSE: You attempted to open the Technology Map Viewer (Post-Mapping), but the Quartus Prime software cannot open the Technology Map Viewer until the post-mapping atom netlist is generated.

ACTION: To generate the atom netlist, either perform Analysis & Synthesis for normal compilation, or perform a partition merge for incremental compilation. After the atom netlist is generated, the Technology Map Viewer displays the data.
