1.4.1. Fast Sim Model for FGT Variants

To provide a reduction in a real-time simulation duration, you can utilize a Fast Sim model in your design example testbench. Available for the FGT variants only, the model is enabled by a macro in the simulation run script.
To enable the Fast Sim model, add the following macro to your simulation run script: 
+define+IP7581SERDES_UX_SIMSPEED
The design example simulation script enables the macro by default for all variants with the exception of variants with enabled PTP or auto-negotiation and link training.
  • In PTP variants, the macro is not enabled by default as it affects the timestamp accuracy in simulation. If you want to perform a general functionality check, you can enable the macro in your PTP simulation scripts.
  • The macro is not available for designs with enabled auto-negotiation and link training.

You can also add the macro to your simulation script for your own testbench.

Attention: In 53G PAM4 Ethernet IPs, you must set the serial clock input to the IP to the exact value of 37.648 ps for simulation to work correctly. This limitation does not apply to the design example simulations since the serial lines are in a loopback.
