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

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.

Workaround/Fix

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
