Why are some simulation library files missing when compiling for Questasim*? - Why are some simulation library files missing when compiling for Questasim*? Description Due to a problem in Simulation Library Compiler in the Quartus® Prime Standard Edition Software 23.1 and later, you may see some Quartus® Simulation Library source files not included for compilation for Siemens* Questasim* Tool selection. This problem persists on both EDA Simulation Library Compiler GUI and command line versions. This problem only exists in Quartus® Prime Standard Edition and does not affect Quartus® Prime Pro Edition versions. Resolution To work around this problem, follow these steps: 1. Edit file: <QUARTUS INSTALLATION DIRECTORY>/quartus/common/tcl/internal/simlib_comp.tcl 2. Replace: set gl(primary_tool,questasim) questasim With: set gl(primary_tool,questasim) modelsim This problem is scheduled to be fixed in a future release of the Quartus® Prime Standard Edition Software.
