EMIF ip fetches error while simulating in vcs

I tried to simulate the emif IP, but it shows below error: 227213 ns: ERROR: iossm_bf_cpu_cpu_test_bench/ihp_read is 'x' $stop at time 227212598000 Scope: unex_block_design.emif_s10_0.emif_s10_0.ar...

Dear DChak3,

Thank you for joining this Intel Community.

I believed your design contain Intel® Stratix® 10 HPS EMIF thus you will see this error is generated. It is a known issue as Stratix 10 HPS EMIF simulation is not supported.

You may refer to this KDB link for more details -->

Thanks

Regards,

Aida

    Hi nuraidaA

    I am not using Intel® Stratix® 10 HPS EMIF instead I am using External Memory Interfaces Intel stratix 10 FPGA IP. It is simulating if I am using this IP with other bunch of IP's. But while I was trying to create libraries using the script provided by quartus. When i select the option from tools>Generate simulator script for IP.

    I ran the script and it shows error mentioned above when it reaches to simulate EMIF IP.

    Reference snapshot attached. The blue circled one is used in the design.
