Error Modelsim-Altera for integer type ports

Hi Sara,

is it possible to perform the functional simulation using integer type ports?

>>Yes, Run full compilation. with libraries

use IEEE.numeric_std.all;

use IEEE.std_logic_signed.all;

The fatal error is related to the type mismatch or libraries used.

We can specify the range of values that an object of type integer is going to have.

Limiting the range reduces the FPGA resources needed to implement the design. Moreover, it gives us a means of checking for errors in the early stages of the design or simulation.

Regards

Anand

Thank you Anand for your reply .

I reproduced the same VHDL codes you provided but i still get the same error.

I attached figures to show you the problem

I have another question. since the integer range is from 0 to 9 , why in the simulation it goes from 0 to 15 ?

Looking forward to reading from you.

Thank you before hand

Regards

Determining the location of the ModelSim executable...

Using: C:\intelFPGA_lite\16.1\modelsim_ase\win32aloem

To specify a ModelSim executable directory, select: Tools -> Options -> EDA Tool Options

Note: if both ModelSim-Altera and ModelSim executables are available, ModelSim-Altera will be used.

Error.

1. recreate the project and check
2. If facing the same issue again use Quartus 18.1 lite.

Anand

Hi Sara,

Try by creating a new project instead of using the same project.

1. Created a simple project with an integer as the port type.
2. Run analysis & synthesis.
3. Created a university program vwf with stimulus and saved the file.
4. run full compilation
5. double click on .vwf and chick on run functional simulation.

If the issue persists try to use modelsim directly.

Regards

Anand

Hi Sara,

Have you solved the issue? Tyr

1. Delete db, incremental_db and simulation folder from the project directory.
2. Run a full compilation of Quartus project.
3. Include the numeric library.

Regards

Anand
