ID:11912 Can't open the RTL Viewer without performing Analysis and Elaboration
CAUSE: You attempted to open the RTL Viewer, but the Quartus Prime software cannot open the RTL Viewer until Analysis & Elaboration finishes processing the design. Performing Analysis & Elaboration generates the RTL netlist, which is needed to generate the data in the RTL Viewer.
ACTION: Perform Analysis & Elaboration and then open the RTL Viewer.
