Due to a compatibility problem between version 22.3 and later of the Intel® Quartus® Prime Software and the Siemens* QuestaSim* 2021.4, 2022.4 tool, simulation of the P-tile Avalon® Streaming Intel® FPGA IP for PCI Express* Design Example testbench will fail to simulation correctly with the following errors:
# INFO: 116032 ns RP User Avmm Driver: begin RP Configuration.
# FATAL: Simulation stopped due to inactivity!
# FAILURE: Simulation stopped due to Fatal error!
# FAILURE: Simulation stopped due to error!
To work around this problem, use Siemens* Questa Sim-64 2022.2.
Starting in the Intel® Quartus® Prime Software version 23.3, solve this issue by adding this command " set USER_DEFINED_ELAB_OPTIONS "-voptargs=\"-noprotectopt\" before running simulation in the Siemens* Questa Sim.
