Hi Taichi,

The problem solved after following your link.

thanks and regards

@sfjiang-astri ,
Did your simulation trial work well?

Hi Taichi,
thanks for your comment, the simulation works well.
And I want to use this tvip-axi as a vip in my verification project.

thanks

You don't need to add -warn_multiple_driver option to make command.

from tvip-axi.

This is a compile option of xrun command.
You can add this option to xrun command to avoid *E,ICDCBA error like below.

Hi Taichi,
some *E,ICDCBA error occurs when i use make command only.

from tvip-axi.

Can you apply following patch to sample/work/xcelim.mk and try again?

Hi Taichi,
which options should I insert in the makefile if i want to dump the waveform of the test?

thanks

from tvip-axi.

I think you need to insert following options for waveform dumping.
https://github.com/taichi-ishitani/tnoc/blob/c16b918b3247874d754a15d9a2b2eb5d911e042c/sim/common/xcelium.mk#L78

from tvip-axi.

I insert the options from line 42 to 57 in the xcelium.mk shown in the figure.
while I cannot dump the waveform in simvision after running the command
'make SIMULATOR=xcelium default DUMP=on GUI=on'

from tvip-axi.

$ make clean; make SIMULATOR=xcelium DUMP=shm

This is correct command.

from tvip-axi.

Thanks Taichi,
while it seems the clock didnot starts to work.

any options should I insert when running the command.

from tvip-axi.

I think this option may be needed.

But I'm not sure.

OK, no problem.
Please feel free to ask question, feedback, feature request if you have :)

@sfjiang-astri
Did -run option resolve the problem simulation does not start?

Yes, It works.

Thanks!

Thanks!

by the way, what is the meaning for "-warn_multiple_driver" when using the xrun simulator?

thanks

from tvip-axi.

For SystemVerilog, assignment having multiple drivers such as the following is not allowed and xrun will raise *E,ICDCBA error.

byte a, b, c;
always_comb a = b; //driver 1
always_comb a = c; //driver 2

The -warn_multiple_driver option is to change severity of *E,ICDCBA error to warning.

In case of the sample TB, I don't know why *E,ICDCBA error is happened.
I'm not familiar with Xcelium because I use VCS mainly so I use -warn_multiple_driver option to ignore *E,ICDCBA error.

from tvip-axi.

I see. So it is used to change the *E, ICDCBA error to the warning.
thanks and regards
