ID:11885 Perform Analysis and Synthesis before opening the Technology Map Viewer.

CAUSE: You attempted to open the Technology Map Viewer, but the Quartus Prime software cannot open the Technology Map Viewer until the atom netlist is generated. To generate the atom netlist, you must 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.

ACTION: Perform Analysis & Synthesis for normal compilation or perform a partition merge for incremental compilation, and then open the Technology Map Viewer.
