Warning: CONV_INTEGER: There is an 'U'|'X'|'W'|'Z'|'-' in an arithmetic operand, and it has been converted to 0.

Environment

    Quartus® II Software
    DSP Builder for Intel® FPGAs Pro Edition
    DSP
BUILT IN - ARTICLE INTRO SECOND COMPONENT
Description

You may get this warning when simulating some DSP Builder® designs under Modelsim®. These warning messages do not have any effect on your simulation results, and can be ignored.

Resolution

These warnings (and all others like them) can be suppressed by either of two methods:

  1. Suppress via Modelsim GUI:
    • Open the Simulation dialog box (Options menu).
    • Set the option Suppress Warnings from Synopsys Packages to On.
    • Click OK.
  2. Search for the *_atb.do file in your project directories, look for the comment "Disable some warnings ...", and comment out a later line as follows:

# Disable some warnings that occur at the very start of simulation
    quietly set StdArithNoWarnings 1
    run 0ns
#    quietly set StdArithNoWarnings 0
    run -all
