Due to a problem with the 25G Ethernet Intel® FPGA IP in the Intel® Quartus® Prime Pro Edition Software version 18.1, the design example with "enable 10G/25G dynamic rate switching" selected might stop unexpectedly in the ModelSim* simulator.
The ModelSim transcript stops at the following simulation stages:
- # Switching to 25G mode : 25G Reconfig start
- # Switching to 25G mode : 25G Reconfig End
- #Waiting for RX alignment
To work around this problem, modify run_vsim.do of the design example in the following directory:
In run_vsim.do, find "elab" and replace with "elab_debug"
- elab to elab_debug
This problem is scheduled to be fixed in a future version of the Intel® Quartus® Prime Pro Edition Software.
