Cannot access $ieee in modelsim.ini

Hi,

We are certain that we had good Quartus and modelsim installation, and inside modelsim.in:

[Library]

std = $MODEL_TECH/../std

ieee = $MODEL_TECH/../ieee

verilog = $MODEL_TECH/../verilog

vital2000 = $MODEL_TECH/../vital2000

std_developerskit = $MODEL_TECH/../std_developerskit

synopsys = $MODEL_TECH/../synopsys

modelsim_lib = $MODEL_TECH/../modelsim_lib

sv_std = $MODEL_TECH/../sv_std

although the above variables are defined, they cannot be printed with "set"

set ieee# can't read "ieee": no such variable

only the following variables, which are listed in to "ModelSim® User's Manual, v10.5b", are accessible, but many are not defined in modelsim.ini

Simulator Control Variables

As with GUI Mode and Command Line Mode, simulator control for Batch Mode simulation is governed by which modelsim.ini variables are enabled and each variable’s setting.

AccessObjDebug IgnoreSVAError StdArithNoWarnings

BreakOnAssertion IgnoreSVAFatal UserTimeUnit

CheckpointCompressMode IgnoreSVAInfo PrintSimStats

ClassDebug IgnoreSVAWarning WildcardFilter

DefaultForceKind IgnoreWarning WLFCompress

DefaultRadix IterationLimit WLFFilename

DelayFileOpen NoQuitOnFinish WLFMCL

ForceSigNextIter NumericStdNoWarnings WLFOptimize

GCThreshold OnBreakDefaultAction WLFSizeLimit

Is this behaviro (not all modelsim.in variables accessible, whereas other variables not defined within modelsim.ini are accessible) by design?

    Hi,

    Have you used

    SYNTAX:set ieee= directory?

    Can you attach the transcript?

    Let me know if this has helped resolve the issue you are facing or if you need any further assistance.

    Best Regards,

    Anand Raj Shankar

    Hi,

    The correct Tcl grammar would be "set ieee directory", without assignment symbol. The line inside the default installation generated modelsim.ini is "std = $MODEL_TECH/../std". Here is the full .ini:

    After launching modelsim, what is weird is that

    >set ieee# can't read "ieee": no such variable

    but we can assign and read back:

    set ieee "C:/intelFPGA_lite/16.1/modelsim_ase/std"# C:/intelFPGA_lite/16.1/modelsim_ase/std

    set ieee# C:/intelFPGA_lite/16.1/modelsim_ase/std

    So it seems that the line for ieee in modelsim.ini was ignored. Should that be?

    Hi,

    Yes, you are correct we are not able to read directly by using set IEEE.

    But we can see simulation libraries are loaded/read automatically by vsim with help of environment variable( MODEL_TECH).

    example: 

    # vsim -c top
#  Loading .../modeltech/sunos5/../std.standard
#  Loading work.top(a)
#  Loading work.for_model(a)
#  Loading ./for_model.sl
#   myentry = $MODEL_TECH/xyz
#   myentry = .../modeltech/sunos5/xyz
#   std =  $MODEL_TECH/../std

    Best Regards,

    Anand Raj Shankar
