In the AMS Designer simulator and Xcelium simulator with the mixed-signal option, both module path delays and interconnect delays are simulated as transport delays by default. There is no command-line option to enable the transport delay algorithm. You must, however, set pulse control limits to see transport delay behavior. If you do not set pulse control limits, the software sets them equal to the delay by default; no pulse having a shorter duration than the delay passes through.
To set global pulse limits for both module path delays and interconnect delays, use the -pulse_r and the -pulse_e options when you invoke the elaborator.
Full pulse control is available for both types of delays. You can:
- Set global pulse control for both module path delays and interconnect delays
- Set global pulse limits for module path delays and interconnect delays separately in the same simulation
- Narrow the scope of module path pulse control to a specific module or to particular paths within modules using the
PATHPULSE$specparam - Specify whether you want to use On-Event or On-Detect pulse filtering
