5.2.2. Simulating Transport Delays

By default, the Active-HDL or Riviera-PRO software filters out all pulses that are shorter than the propagation delay between primitives. Turning on the transport delay options in the in the Active-HDL or Riviera-PRO software prevents the simulator from filtering out these pulses. Intel® Arria® 10 devices do not support timing simulation.

Table 12.  Transport Delay Simulation Options
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.
To perform a gate-level timing simulation with the device family library, type the Active-HDL command:
vsim -t 1ps -L stratixii -sdftyp /i1=filtref_vhd.sdo \ 
work.filtref_vhd_vec_tst +transport_int_delays +transport_path_delays
