help : VCS compile XILINX IP:Error-[URMI] Unresolved modules

Jump to solution

Hi!

I have trouble with cosimulation of Vivado and VCS. The problem happens in VCS elaboration when MIG IP is being compiled. One of the error is as below:

 

Error-[URMI] Unresolved modules
./../../../mig_7series_0_ex.srcs/sources_1/ip/mig_7series_0/mig_7series_0/user_design/rtl/clocking/mig_7series_v4_0_iodelay_ctrl.v, 282
" BUFG clk_ref_300_400_en.clk_ref_400.u_bufg_clk_ref_400( .O (clk_ref[1]),  .I (clk_ref_mmcm_400));"
  Module definition of above instance is not found in the design.

 

Of course, there are ten more errors like this and the log is attached.

 

I might have some clues that VCS cannot find those module in XILINX IP library. But where can I find those specific libraries and what kind of switch should I use to add the path ?

 

Regards!

Hi @li_zicong,

 

Did you follow UG900? Did you compile the simulation libraries (p15)?

Thanks for your reminding. Yes, I did as what the guide you provided tells me except generating a netlist to simulate, but is it necessary to generate a netlist for simulation ? Besides, I also precompiled the simulation library for VCS and set the path right. 

 

Software compatibility has been checked according to vivado-release-notes-install-license.pdf

OS:Centos 6.8

Vivido version: 2016.4

VCS version: vcs-mx_vL-2016.03

Hi @li_zicong,

 

No you shouldn't need the netlist for behavioral simulation.

 

Did you try to launch the simulation from vivado? (configure VCS as targetted simulator).

 

Also from the UG973, the supported VCS version for vivado 2016.4 is VCS 2016.06:

You might need to move to VCS 2016.06.

 

Hope that helps,

 

Regards,

Sorry, my typing error. My VCS version is vcs-mx_vL-2016.06. I found out my stupid setting error because of your suggestion, specifically VCS installation path and compiled simulation library path. Thank you anyway.

 

This problem disappears and the other arrise. I gotta work on it now!
