FIR II ip simulation warning

I’m using Intel Quartus prime lite edition and I’m getting the following frequent/multiple warnings when simulating the FIR II IP using Questa Intel starter FPGA edition:

Warning: NUMERIC_STD.TO_SIGNED: vector truncated

# Time: 7750400 ns Iteration: 1 Instance: /tb/DUT/FIR_I/DUC_FIR_ast_inst/real_passthrough/hpfircore_core

What could be the cause? I tried to apply the solution mentioned in the link below but I couldn’t locate the file:

https://www.intel.com/content/www/us/en/support/programmable/articles/000092740.html

Kindly, advise.

    Hi,


    Can you please check once more in the path mentioned below.


    <ip_variation_name>folder/altera_fir_compiler_ii_1911/sim/


    Please let me know if you are still not able to find it.


    Thank you

      Hi,

      I searched the entire computer. The folder (altera_fir_compiler_ii_1911) and the file (hb1s_altera_fir_compiler_ii_1911_kmsq6ua_rtl_core.vhd) don't exist. There is a folder called (altera_fir_compiler_ii) in the path:


      C:\intelFPGA_lite\22.1std\ip\altera\dsp

      But it doesn't contain the file. Kindly, advise.

      Regards,

      Fuad

      Hi K**bleep**ij,

      Herewith the relevant project files. Open the project DUC and then RTL simulation and the simulation will run automatically then you will see the following multiple warnings printed in Questa:

      # ** Warning: NUMERIC_STD.TO_SIGNED: vector truncated

      # Time: 5228800 ns Iteration: 1 Instance: /tb/DUT/FIR_I/DUC_FIR_ast_inst/real_passthrough/hpfircore_core

      # ** Warning: NUMERIC_STD.TO_SIGNED: vector truncated

      # Time: 5230080 ns Iteration: 1 Instance: /tb/DUT/FIR_Q/DUC_FIR_ast_inst/real_passthrough/hpfircore_core

      I’m using Quartus Prime Version 22.1std.0 Build 915 10/25/2022 SC Lite Edition and the operating system is windows 11. Kindly advise.

      Regards,

      Fuad

      Hi K**bleep**ij,

      Correction: I'm using Windows 10 Pro.

      I'm currently using Quartus Lite Edition so there is no Q22.4 or latter versions. The latest Lite version is 22.1.1 (according to Intel website).

      Is there a solution for the warnings in the Quartus Lite Edition? We are planning to upgrade to the pro edition but not at the moment.

      Kindly advise.

    Hi,


    I would suggest to move to Q22.4 pro edition or later version to resolve this issue.


    Thank you

      Hi K**bleep**ij,

      My personal Email is mentioned in this public case and I'm getting a lot of spams because of this. Is it possible to remove the part where my Email is mentioned?

      Regards,
