How do I perform VHDL simulation for the altchip_id megafunction? - How do I perform VHDL simulation for the altchip_id megafunction? Description The Quartus® II software version 13.1 and earlier only has VHDL simulation support for the altchip_id megafunction for the Modelsim simulator. A Verilog HDL simulation model for the altchip_id megafunction is available for all supported simulators. Resolution If you require simulation support for the altchip_id megafunction for any simulator other than ModelSim, you are required to use the Verilog HDL simulation model. VHDL model support is scheduled to be added for non-ModelSim simulators in a future release.
