How can I access the RTL Netlist in the Quartus® Prime Pro Edition Software? - How can I access the RTL Netlist in the Quartus® Prime Pro Edition Software? Description One of the packages documented in the Quartus® Prime Pro Edition User Guide - Scripting , the Quartus® Prime Tcl API Help browser , and the Quartus® Prime Command-Line for versions 21.2 and earlier is "RTL." The RTL package commands require the "quartus_map" executable, which is unavailable in the Quartus® Prime Pro Edition software. When you execute any command from this package, the Tcl console displays the following error: ERROR: Can't read compiler database. Run the Analysis and Synthesis (quartus_map) successfully before using this command. Resolution To work around this limitation in Quartus® Prime Pro Edition Software versions prior to 23.3, you can access the timing netlist from the STA package, which provides similar functionality for querying netlist information. For additional details, consult the Quartus® Prime Pro Edition User Guide - Scripting . Otherwise, starting with the Quartus® Prime Pro Edition Software version 23.3, introducing the Design Netlist Infrastructure (DNI) allows users to traverse the Design Netlist using Tcl commands. This provides a new method for accessing netlist information without relying on the RTL package. For detailed instructions, consult the Quartus® Prime Pro Edition User Guide: Design Compilation .
