2.2.5. Simulating Transport Delays

By default, the ModelSim and QuestaSim software filter out all pulses that are shorter than the propagation delay between primitives.

Turning on the transport delay options in the ModelSim and QuestaSim software prevents the simulator from filtering out these pulses. Intel® Arria® 10 devices do not support timing simulation.

Table 7.  Transport Delay Simulation Options (ModelSim and QuestaSim)
Option Description
+transport_path_delays Use when simulation pulses are shorter than the delay in a gate-level primitive. You must include the +pulse_e/number and +pulse_r/number options.
+transport_int_delays Use when simulation pulses are shorter than the interconnect delay between gate-level primitives. You must include the +pulse_int_e/number and +pulse_int_r/number options.
Note: The +transport_path_delays and +transport_path_delays options apply automatically during NativeLink gate-level timing simulation. For more information about either of these options, refer to the ModelSim-Intel FPGA Edition Command Reference installed with the ModelSim and QuestaSim software.
The following ModelSim and QuestaSim software command shows the command line syntax to perform a gate-level timing simulation with the device family library: 

vsim -t 1ps -L stratixii -sdftyp /i1=filtref_vhd.sdo work.filtref_vhd_vec_tst \
+transport_int_delays +transport_path_delays
