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,

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,
