Why do I see an incorrect read latency when simulating the eSRAM Intel® Stratix® 10 FPGA IP?

You may see an incorrect read latency when simulating the eSRAM Intel® Stratix® 10 FPGA IP because the IP instantiates a gate model CPA block for simulation, which can cause a hold violation at the PHY interface.

To work around this in simulation, do the following.

1. Open  IP_generated_dir/esram_<>/sim/<>_esram_191_<>.sv

2. Search   defparam    fourteennm_cpa_component.pa_sim_mode    = "long"; 

3. Change to defparam    fourteennm_cpa_component.pa_sim_mode    = "short"; 

This problem is fixed starting with the Intel® Quartus® Prime Pro Edition software version 20.1.
